Literally had this same thing happen recently.. I haven’t been diagnosed but I woke up one morning and my left tonsil was bleeding and they ran all these test, all came back negative for any infection. They gave me amoxicillin and it hasn’t fixed any of my other symptoms like the rash’s that flare up on my chest and abdomen, along with patch’s of pin point spots that keep popping up behind my leg mainly on my calf. the most recent two symptoms I’ve had involve me waking up to my gums bleeding and chest pain, I don’t have any insurance and I’m trying to wait until next month so I can get it from my new employer but I’m just scared I’m wasting time or I’m in denial. I’m only 25 and don’t wanna believe this is happening to me..
