I was in a terrible car accident causing me to be in the hospital for one month and now leaving me on Plavix for 5 months so far. i have had many of the side effects; nausea, dizziness, fatigue, easy bruising etc. but lately something came up that shocked me, i don't know how long they have been there for, but my throat had been hurting for about 2 weeks and i looked in my mouth and saw white lesions and ulcers in my mouth. The first thing i did was go to the doctor, because i do have a boyfriend and you never know right? The doctor told me it was herpes, and did a swab of the infected area. He also told me, even if the test comes back negative it's still herpes and that it would be gone in about a week since i probably had already had it for about 2 weeks. i talked to my boyfriend, we waited it out, its been almost 2 months now. I don't know if there is still a possibility of herpes, but i read on a few places in small cases stomatitis is a side effect in people, and since stomatitis causes lesions and ulcers sometimes... is it possible its from my medication?
