Hi,
Noted your history well and understood the concerns.
Since the sex happened 3 months ago and you have developed
sore throat and
balanitis now means the cause can also be recent one.
I would advise you the following in such a situation:
Gargling with antiseptic.
Consult an ENT Surgeon for proper evaluation and get treated with a course of anti-inflammatory as per his advise.
A for
balanoposthitis cleaning multiple time with plain water, application of
povidone iodine should help.
If this does not help then consult your Doctor for proper clinical evaluation, examination, tests of blood for STD panel,
diabetes and as would be advised to get a possible diagnosis and management .
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
