My legs have been getting weaker for a while. Though its only recently that i would describe my legs as weak. Previously, my legs were not strong, but sufficient i suppose. The last month or so i've noticed that they are much weaker and today especially i have noticed how weak they are. My legs feel like they are all bone and no muscle. Walking is harder, i cant lift my legs up, so they almost skid along at times, and i feel them shaking pretty much all the time, very small, but constant shuddering. Im finding it quite destressing because ive had this illness four years now, and if things continue as they are then i cant see myself being able to walk/stand at all in another four years time. Perhaps much sooner than that. Is there any knowledge as to why this is happening, and anything i can do about it? Im reluctant to go to my GP who im pretty sure wont be able to do anything about it.
