Consider other causes; treatment will vary
Detailed Answer:
Hello and welcome.
Thank you for writing in.
Usually a sore(s) on the penis is seen in association with genital herpes, but if you have repeatedly tested negative for herpes tests, then you should consider requesting your doctor to look for other conditions that can cause a sore on the penis:
-Gonorrhea (treated with antibiotics)
-Chlamydia (treated with antibiotics)
-Syphilis (treated with specific-antibiotics like penicillin's)
-A simple benign growth called a wart (treatment depends on type of growth and extent of involvement)
The medication you are currently on (i.e. acivir) would be appropriate if you were seeking treatment for herpes; but as there are other possible causes on the list you should visit your doctor and find the exact cause, and accordingly get treated.
I hope I have succeeded in providing you information on the other possible causes and how treatment varies in each case. Please feel free to write back to me for any further clarifications.
Best wishes.
