Hi everyone, I have a wonderful friend who has fibromyalgia. During the past 2 weeks, she has pulled many muscles in her back by doing relatively simple, day to day things. This isn't just the "normal" pain she goes though daily, or a back ache, or pain from overdoing it. Its in specific muscles in her back, that she is pulling by doing simple things such as bending over to pick something up. Tonight she pulled another muscle that she said made her almost fall to her knees. She isn't sure if it is the fibro that is causing this is what. She is in alot of pain, and right now afriad to even move, and this is breaking my heart to watch her in such agony. Do you guys think this is fibro related, and any suggestions on how to help avoid this, make the pain better. Also; She had blood tests not long ago, and it said she was low on Potassium. Could this be causing her so much pain? Thanks!
