I will do a general reply to all of this, as I suffer from the same issues. I do have some definitive diagnoses; but, the ultimate one you all and I am looking for, I am sorry to say, I don't have. I am hopeful that I am getting closer. But, to quickly answer your question about tick bites...that was one of my first thoughts. I have been bit many times over the years considering I have spent much of my childhood outdoors and in the woods. Therefore, I did have my PCP check me for Lyme Disease and it was negative.
