Im a 31 year old male who recently returned from Peru (Iquitos) April 1st after spending about 2 months there. While I was there I tried coke 4 times and had unprotected sex with two local girls. I came back home and 3 days later, my life has literaly gone to hell since then. For the past 2 weeks I have had near constant fatigue, brain fog, general feeling of malaise, restlessness, insomnia. Other symptoms that come and go include lower abdominal pain, diarrea, depression, general out of body experience, anxiety attacks. I have always been a very healthy person in the past, the longest I would ever get sick for was 2 or 3 days that's why these two weeks have been so scary (partially explains the anxiety attacks I guess?). I did not get any shots before going to Peru (very stupid I know). I have been to the ER three times when the symptoms really got out of hand, they simply did a quick blood test and sent me on my way. I have been to my doctor several times and a tropical disease specialist aswell. Neither of them have been able to find anything wrong with me. My blood work has come back perfect every time (no strange white blood cell readings, no hepetitis or HIV either), my stool samples also came back negative for any parasites as did my urine tests. When I first started experiencing these symptoms it was very sudden, like a total immune system crash... Last week on Tuesday, I started feeling abit better when suddenly at night the same exact thing happened again. When I first saw the specialist he gave me anti maleria medication just to be sure it was not a possibility (even though I tested negative for it). I'm completely clueless as to what this could be, I don't think it's a bacterial infection since my white blood cell count is normal, I know it's not malaria, Im not sure if it's parasites (just to be sure I have purchased a colon cleansing kit and started the program). The specialists best guess is that it's viral that I should wait it out, which I want to if the symptoms weren't so intense. I realize I did a whole bunch of dumb things, I just never though anything could ever touch me. Has anyone experienced any similar symptoms or have an idea where I should start looking, please please help.
