Fasciculations, pins and needles due to uncomf. positions, nocturnal body jerks, hand cramps, abs cramps when bending down, dizziness, shortness of breath some parts of skin feel oversesitive when touched. is it ms? there is no weakness, paralysis rn?

Those symptoms aren't classic MS ones. Have you been tested for deficiency of calcium,magnesium or electrolyte imbalance? Some of your symptoms may be triggered by physical or psychological stress. Have you consulted a neurologist for evaluation & advice. If not, I recommend you do. Appropriate testing will be ordered.

None of what you describe is characteristic of a presentation of MS, and most of the symptoms seem to involve peripheral nerves and muscles. A neuromuscular specialist or a neurologist would be a good resource to evaluate your problems.
