I know that water exercise (swimming, water-walking, etc.) is highly recommended for fibromyalgia. For MS (which I also have), too. I have two concerns. First, I sometimes get very cold, even in a heated pool. I'm okay in a jacuzzi (which should be bad for my MS, but which makes me feel wonderful!), but in a swimming pool, I sometimes get so cold my teeth start chattering and my jaw tenses up, adding to my TMJ pain. And the last few times I actually tried to swim, my shoulders got evern more sore than usual, and I felt miserable. (I don't usually have access to a pool, and this was admittedly quite a while ago. But it kind of spooked me.) My second concern is a little difficult for me to talk about, but I'll give it a try, since some others also may have similar worries. I have IBS. I also have MS, as noted previously. I get myoclonic jerking associated with my MS, which two neurologists have suggested might also be affecting my bowel. Also, my MS tends to provide very short notice regarding bowel and bladder needs. With MS, nature doesn't call; it screams! For all these reasons, I worry about having a sudden urge when I'm in the pool and not being able to reach a bathroom in time. I don't expect many others on this list to be contending with the MS part of my problem, but I know that IBS is common among people with fibromyalgia. Maybe what works for you could help me, too. How do you "protect yourself" against IBS problems when you use the pool for exercising? --Laura R.M.
