EMPATH/ HSP --I swear my knee problems began when I was taking care of an older lady w/bad knees--needed help getting to her feet, etc. My own knee pain began when I returned home from that job. Years later am the proud owner and bearer of two bionic knees. Hmmm... was that REALLY the beginning of my "knee problems"? NOW I take care of a lady with heart trouble, and I have been experiencing dysrythmias. GEEEEZ!!! Working on being less sensitive to this stuff.
