I am a 26 year-old healthy female. Until recently, I have had no history of an illness. I had no circulatory, or neurological issues. However, for about two months I have been experiencing a range of intermittent symptoms:
- Initially, I began experiencing a general numbness in my lower legs. I had full range of motion, sensitivity to heat/cold/touch/pain, but it was an overall feeling of heaviness and weakness. There was never any tingling. I saw a doctor after a few days and was referred to a neurologist. The general nerve sensitivity test was normal all over my body.
- The numbness spread over the course of a few days to my upper legs as well, and my arms. Again, it was more of a tired/heavy feeling. This began to dissipate after about 2.5 weeks. I had a brain MRI, the results of which were normal.
- I was relatively symptom-less for a few days, and then I began to notice that when I laid flat on my back or reclined on my back (at an angle, like on a couch) my hands would slowly become numb and eventually start to tingle. This was always easily remedied by moving positions to my side or sitting up. It seemed like a circulatory issue, but one would expect that lying flat on one's back would be one of the least-restrictive positions for circulation.
- Recently the tingling in my hands has been less frequent, even when lying on my back. I had a second brain MRI, the results of which were also normal.
- This morning my left thumb began twitching involuntarily. I can stop it by tensing the muscle or applying pressure with the thumb to something. Coincidentally, I am actually going in for a spinal cord MRI this evening. Because all my symptoms had been decreasing I was beginning to wonder if whatever had been going on had simply passed, but now I am (of course) getting concerned again.
Does anyone have any similar experiences or suggestions as to what may be going on?
