There is numbness, tingling and pins and needles on the face, palette, arms and legs. There are frequent cramps in the abdominal area. Feeling of tightness in the arms and legs at times. Problems with hand co-ordination . And lightheadedness or vertigo. Along with mood swings, body tightness and bladder incontinence. There is also constipation. I'd like to know the probable diagnosis behind these symptoms. The onset was gradual.
