Every few months I get extremely ill. The symptoms are hard to describe but they get worse each time I have this illness. For the past year I ve had a pain in my right kidney area during these illnesses. My Dr has checked my urine & nothing seems amiss. The last time I got sick was in February. It started with excruciating head & face pain, which lasted about three weeks. Then I had the same illness return with a vengeance. I really didn t think I d make it through this time. It took me a couple of months to get my strength back and now I m terrified for the next time this mystery illness arrives. I do have parts of my skin that have darkened & small brown spots appeared on my legs. Not sure if this has anything to do with my illness or not.
