Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have a
fungal infection in the
scrotum and penis and it seems to be secondary to antibiotic intake that is
bactrim that you have taken every time you experienced the symptoms..
It seems to be Mucocutaneous Thrush leading to the symptoms of burning, redness and itching severely..
I would suggest you to consult an Internal Medicine specialist and get evaluated and a thorough clinical evaluation and investigations like urethral swab culture can help in diagnosis and treatment can be done accordingly..
You can be advised to apply antifungal ointment over the infected areas and along with it an
oral antifungal medication course like
Fluconazole can help..
In case if you are sexually active or married the same treatment can be given to your wife/partner..
Along with it take probiotics like Yoghurt and also keep the area clean and dry..
Take Levocetrizine for itching and redness.
Hope this information helps..
Thanks and regards.
