I used to have a mild itch in my urinary track be4 but a doctor at a point administered erythromicin injection and immidiately my anus was invaded with terrible itching rashes. The itching in my urinal pipe increases terribly which I have been trying to controlling since then. The urinal track is itching , my anus is itching for 5 years now. Anytime I urinate I feel like it should not pass the track. Many test were run on me to check for any STD and any related issues but my doctor keep saying I have no problem but just a reaction/allergy. Also, if I take milk/beverages generally or any soft drinks, it make it worse and again I will be draining and nervous for the next few days. So I have stir clear of it. When the rashes invade my anus, I use BEYTUCEN cream to rub it and the whole thin will clear within 24hrs but since it cannot touch the one inside my urinary pipeline, the itching remains in the track and will come back to my anus again after about 3days of not using it. Please your advice sir and remedy. The Itching is serious and my wife valva and anus is suffering for the same.
