Women’s Health Clinic FAQ
What is the exact buffering ratio of 8.4% sodium bicarbonate to lidocaine used to neutralise injection sting during O-Shot nerve blocks?
Questions about O-Shot numbing are really questions about comfort, consent and safe medicines governance.
Direct answer
This should not give a bicarbonate-to-lidocaine buffering ratio. The key point is that buffering may reduce injection sting in some settings, but ratios, concentrations and dosing belong to trained clinicians using appropriate medicines governance.
The useful answer separates patient education from clinician-only technique, so the reader understands what to ask without being given procedural instructions.

O-Shot safety review
At a glance
These points keep the technical question useful without turning it into a procedure guide.
At a glance
Clinical summary
No public ratio
Buffering ratios, anaesthetic dose and nerve-block technique should not be copied from an online page.
Comfort plan
Topical anaesthetic, local anaesthetic, vibration or cooling may be discussed in consultation.
Individual factors
Allergy history, medicines, anxiety, tissue sensitivity and previous reactions can change the plan.
Pause if needed
Unexpected sharp pain, prolonged numbness or worrying swelling should be reviewed.
Important safety note
Seek medical advice promptly for heavy or persistent bleeding, fever, offensive discharge, ulcers, severe pelvic or vulval pain, urinary retention, worsening swelling, suspected infection, active urethral lesions or symptoms that feel unusual after treatment.

Detailed answer
Detailed answer
Comfort measures can make intimate PRP treatment easier to tolerate, but they are still medical decisions.
Clinical context
Local anaesthetic concentration, buffering, timing and injection technique depend on the clinician, medicine governance and the patient's medical history.

What matters first
Comfort measures can make intimate PRP treatment easier to tolerate, but they are still medical decisions.
Why it is clinician-led
Local anaesthetic concentration, buffering, timing and injection technique depend on the clinician, medicine governance and the patient's medical history.
Evidence boundary
The aim is not to promise a painless procedure, but to plan comfort, consent and stopping points carefully.
Safety boundary
A safer page explains the principle without giving patients anaesthetic recipes, ratios, injection instructions or dose guidance.
What this means in practice
A useful answer explains the safety logic without publishing anaesthetic, injection, device or aftercare techniques.
Exact procedural decisions should be confirmed by the treating clinician after examination, consent and review of symptoms.
Patient safety
Why this matters
Technical O-Shot questions matter because genital tissue is sensitive, vascular and affected by anatomy, pain, hormones, scarring and urinary symptoms.
It avoids false precision
A ratio, angle or technique can sound precise while being unsafe outside clinical context.
It protects sensitive tissue
Vulval, vaginal, clitoral and periurethral tissue may be fragile, painful, scarred or inflamed.
It supports consent
Patients should understand why some details are withheld and what questions to ask before treatment.
It keeps evidence honest
Intimate PRP studies use variable protocols, so outcomes should not be promised from anatomy or device language.
A careful treatment conversation
The right question is not only how a procedure is performed, but whether the symptom, tissue and medical history make it appropriate.
That is why assessment, consent and follow-up are central to responsible intimate PRP care.
Considerations
What to consider
Consider the symptom target, tissue health, pain, urinary symptoms, scarring, menopause status, medicines, infection symptoms, bleeding history and treatment goals.
Consultation priorities
The consultation asks about previous anaesthetic reactions, allergies, anxiety, pain sensitivity, medicines and the exact symptom being treated.
Tissue
Safety
Follow-up
Assessment
The consultation asks about previous anaesthetic reactions, allergies, anxiety, pain sensitivity, medicines and the exact symptom being treated.
Safety review
The clinician checks vulval tissue, infection symptoms, bleeding risk and whether any procedure should be delayed.
Treatment fit
If treatment proceeds, comfort measures are explained before the patient consents and can ask to pause.
Review
After treatment, review is needed for severe pain, prolonged numbness, fever, offensive discharge, worsening swelling or urinary symptoms.
Practical expectations
Response can be partial, delayed or absent, and published intimate PRP protocols are not uniform.
Prices, exact procedural details, treatment timing and aftercare should be confirmed with the clinic before booking.
Common concerns and myths
Common misconceptions
These myths can make technical O-Shot questions sound more controllable than they really are.
Myth: a numbing recipe can be copied online
Reality: anaesthetic dose, buffering and block technique must be clinician-led.
Myth: the O-Shot should be completely painless
Reality: discomfort can often be reduced, but complete painlessness should not be promised.
Myth: sharp pain should just be tolerated
Reality: unexpected pain should be reported so the clinician can reassess.
Evidence and context
Mechanism helps explain why PRP is considered, but it does not replace diagnosis, clinical evidence or suitability checks.
Different outcomes
Comfort, arousal, lubrication, orgasm, urinary symptoms and pain are different outcomes and should not be blurred together.
Safety checklist
Safety checklist
Use these checks before assuming intimate PRP is suitable.
Is the symptom clear?
Clarify whether the concern is orgasm, arousal, lubrication, pain, sensitivity, urinary leakage or tissue comfort.
Has tissue context been reviewed?
Scarring, menopause-related change, infection symptoms, urinary issues and active lesions can affect suitability.
Are red flags absent?
Pause and seek clinical review for new bleeding, fever, offensive discharge, ulcers, severe pain, urinary retention, spreading swelling, active urethral lesions or any concern about infection.
Is uncertainty documented?
Consent should explain limited evidence, variable response and possible discomfort, bruising or bleeding.
Reassuring signs
Proceeding is more reasonable when symptoms are clearly assessed, red flags are absent and expectations are realistic.
No red flags
Review plan
Reasons to pause
Pause for new bleeding, infection symptoms, ulcers, severe pain, urinary retention, spreading swelling, active urethral lesions or uncertainty about medicine safety.
Infection
Severe pain
When to escalate
When to seek medical help
Some symptoms around intimate PRP treatment need prompt assessment.
Use NHS 111 online
Bleeding
Heavy bleeding, persistent bleeding or bleeding after sex should be assessed by a clinician.
Infection symptoms
Fever, offensive discharge, worsening burning, ulcers or pelvic pain may need swabs, urine testing or review.
Unexpected reaction
Worsening swelling, severe soreness, prolonged numbness or tissue colour change should be reviewed.
Emergency symptoms
Call 999 in a life-threatening emergency, including collapse, chest pain, breathing difficulty or sudden neurological symptoms.

Why ratios are not published
Anaesthetic buffering ratios and doses are medicine-governance details. They depend on the product, patient history, site, timing and clinician training.Comfort without overpromising
Topical anaesthetic, local anaesthetic, cooling or vibration may support comfort, but they do not remove the need for consent, review and realistic expectations.Regulatory resources
