6 months ago I got a concussion after a fall. Since then I've felt at times like I was going crazy trying to figure out what is wrong with me. I'm an otherwise healthy 30 year old woman. I've had a CT and a MRI and seen 2 neurologists, both of whom said everything was "normal" and I was just stressed out.
I had some symptoms that seemed "typical" of a concussion for the first few weeks, like trouble concentrating and light sensitivity, but those went away completely. What I was left with was severe nausea, a feeling of not being myself/random crying at times, and a sense of weakness (without actually being weak if that makes sense.) The stomach problems have persisted with IBS like symptoms. I've seen a GI and had an endoscopy, which like everything came back normal. After about 4 1/2 months things seemed to improve a lot, but then 3 weeks later the stomach issues returned. Also, the feeling of shakiness/weakness came back. It is not aggravated by physical activity, but I'm afraid to exercise because of the sensation that I'm going to collapse. It sometimes feels like I've lost touch with my own physical signals.
I've searched everything I can find on PCS but it usually just talks about things like headaches. I don't know where else to turn or what kind of test I might need. I'm afraid that something else is wrong because I don't know if what I'm feeling is PCS. Can PCS primarily be stomach issues? Has anyone ever felt this sensation of being very weak at random times? I have days that are pretty good, too, but the bad days are really keeping me from living my life sometimes.
