I'm between neurologists (next appt. w/new one is not until April) and my PCP won't be helpful, so here goes: two weeks ago, my left leg began waking me at night with pain, spasms and stiffness. The spasms moved around: sometimes the calf, sometimes the inner thigh, sometimes the foot with toes curling, sometimes the whole foot pulling up and not responsive when I tried to flatten it. About the same time, the left knee, no warning or pattern, would suddenly weaken. This past week, the inside of the knee has been very painful, at first constantly, now only when I try to raise my leg too high (e.g., when putting on shoes). I've been working around the problem, but today that leg has felt hot when I stand for longer than it wants to, then prickly. I try not to complain or bother disinterested doctors, but this is really getting on my nerves (hahahaha). I do have lesions on my cervical and thoracic spinal cord as well as on the brain, but haven't had a spinal cord MRI for 2 yrs, at which time nothing was active. I know in advance that most of us here are not doctors, but what does this sound like?
