I don't think its MS eventhough a lot of times it can be cured with mercury chelation using cutlers protocol. I think if I had MS I would know for sure because the tingling only appears rarely. I have chronic mercury toxicity and this can mimic MS symptoms too
On another note. Before I was with that girl I took a natural supplement called forta for men and it turns out it was recalled due to finding traces of tadalafil in it. Some of the side effects there actually match with the pain I was experiencing. Not sure though.
