Why is my foreskin a little red?

Hi doctor,

I am suffering from a small reddishness in my glans and foreskin. Due to friction, it becomes redder and clearly seen, or otherwise, it becomes normal. But the one mild reddish small patch on the glans has been for a year without any pain or irritation. Once, I had oral sex and accidentally got hard teeth scratched on my glans but without any cut. It was just a hard scratch. So I doubted it may be because of that and consulted a sexologist. He suggested sexually transmitted disease torch tests, virus research and diagnostic laboratory, human immunodeficiency virus test, and urine test. The results were negative for all the parameters, but toxoplasma G is positive and high, and in urine analysis, bacteria are also detected. So the doctor suggested because of toxoplasmosis, you are getting reddishness in your foreskin, and he prescribed Valacyclovir hydrochloride 1000 mg and Levocetirizine combined with Montelukast for a month, one tab daily at night. I do not know how long it may take for the reddishness to disappear in the foreskin. It has been 20 days on medication, but I still find that mild purple-like reddishness in my glans, as attached in the image where I had a teeth scratch and my foreskin became red. I doubt whether it is because of hard, sharp teeth scratches or toxoplasmosis and how long it will take to heal. What should be done about this? Please help.

Hello doc,

Thank you for your reply. It has been a year since it became red when subjected to friction and becomes light red. It may be because of those hard teeth scratches 1.5 years ago. So I consulted the doctor, and he prescribed these tests and medicines. I have been taking medicine for the last 20 days. I also used Clotrimazole ointment several times whenever it became reddish, but I could not find any solution. It remains light red in the foreskin and glans and sometimes sudden bright red. Please advise.

Hi doctor,

Thank you for your reply. Will the already consumed medicines for the last 20 days show any side effects? Should I have to consult any doctor about that? I will try Tacrolimus, as mentioned.
