good morning doctor, I am edwin from Australia. I have a concern regarding something. I have being recently diagnosed with herpes simplex (genital) the doctor prescribed valacyclovir 500 mg BD i am also taking medication to boost the immune system. all the blisters that i had around my anus are not as bad as they were two weeks ago when they appeared the first time . the doctor told me to take that antiviral for 10 days, i have already finished it but although the blisters seem to be healing well, I am still feeling the tingling and itchyness around the anal and perineum are. I still also feel it in my penis, scrotum and sometimes in the face, i put zovirax when i feel it around the lips. anyway, should i go back to the doctor for more valacyclovir ? i still have 17 tablets left. do you think i should try another antiviral ? is ti normal to still feel that tingling sensation and itchtyness after 10 days of being on the medication? thank you very much for your help doctor, i really appreciate it
