I have had the same symptoms and for the past two weeks they at first were trying to rule out MS but now they are trying to confirm a diagnosis. Two days ago because of the pins and needles and restless leg syndrome they gave me a prescription for these symptoms and to me it is a miracle drug. I actually slept through for two nights in a row. The drugs name is Gabapentin. It makes you sleepy so it is taken at bed time. They have me on 300mg capsules and I take 1-2 at bedtime. My cat was finally able to lay on my upper leg last night and I didn't have to throw her off. So I would suggest this medication. I don't know what other medications your on so be sure to check for interactions with this drug with the others you may be taken. The medication took away the restless leg syndrome and numbness in my arms and legs along with the pins and needles that I was feeling. Good luck and keep me posted to let me know if you get this and it works the same for you.
