I was in an aerobic class in my 30's and one day I thought I hurt my rib cage from exercising. As I examined my abdomen area I noticed (what I thought were spider bites - by the way, spiders are known to bite not only once but three times) red marks. And yup, I had three extremely painful marks. Well, it took at least 3 months to heal but I suffer for 6 months more internally. Finally, I decided to have a conversation with a physician and he asked me if I ever had chickenpox. Of course I did, but I wasnt aware that my immunity system could be so depleted that I could be a prime candidate for Shingles. I thought this is something elderly people get when they are run down. Very painful, Shingles is too kind of a name given to such a tormenting illness. I actually thought I had cracked my ribs. I will lift your mother up in my prayers.
