Muscles have weakened making it difficult to walk at a normal pace or more than 10 paces without resting. Use of muscle (in my case full body) sends me into flares which consist of burning, aching, throbbing, stabbing , spasms, twitching and pain. Somedays are worse than others of course but I have known and felt my body dying a slow death for over a year now. I use wheel chairs for distance, mats for cushion, alot of heat packing. Made adjustments to cabinets for things to be on low shelf bc I can't reach or lift arms without paying the price. I do stairs very slow with breaks or crawling and plan my trips within my home as to prevent too many up and down the stairs. Work smarter not harder! I say this with ease now... but, look back through my earlier posts and you may find some panic in my voice. Scary stuff. I feel my decline each year and am in fear of where it will end. We are all so very different so dont judge you by me, but it helps to hear what may be the truth for some.
