I work in a small office with 10 coworkers. Every once in a while one of these coworkers will pat me on the back, tap me on the shoulder, etc. After about 6 months of being in terrible pain after each of these episodes, I finally had to bite the bullet. I went to my immediate supervisor to talk about my fibromyalgia. I was trying to hold off, but just couldn't any longer. I asked her to please talk to the staff and let them know that I just cannot be touched - for any reason - due to a medical condition. I stressed to her that I wasn't at all angry at any of my coworkers because obviously none of them knew about my condition either, I just needed her to relay this message for me. It brought me to tears how understanding she was. All of this time I was afraid to bring it to her attention, now I'm glad I did. She talked to the staff, was very discrete, yet compassionate about it, and they are all fine with it. If any of you have this problem at work - don't be afraid to tell your supervisor!!!
