I have questions about EBV that I would like answered. I have EBV and I know that it stays in your system for life, but can it cause other autoimmune disorders or conditions in the future? I had mono in high school (I am 20 now) and ever since I have not felt right. I am constantly aching all over and for the past couple weeks I have been having increasing thigh pain, not sure it its related. I have headaches almost daily, and nausea all the time. I will also sometimes say words wrong for no reason and have anxiety. I have gained weight and can't seem to get it off and sometimes I just don't feel like myself, I feel like something is not right. Also have had occasional heart palpitations where it its actually like I can hear my heart do a flip flop and one loud thump and then it does away. I don't know if anything is connected but I just haven't felt right since. There's probably more symptoms that I can't think of right now. Oh and sometimes it feels like I have pulled muscles all over when I haven't done anything to actually pull those muscles. Previous medical conditions I have had include H. Pylori and chronic sinusitis, medications I take are my birth control Loestrin 24 fe and ibuprofen. If anyone can give me any information it would be greatly appreciated.
