Paraesthesia (Numbness) Keeping Me Awake: Tips?

In the past few weeks I have noticed a significant increase in the frequency and intensity of the Paraesthesia, especially in my arms and legs. It has been keeping me up and/or waking me up at night as it is painful at times as it is tingling (hope that makes sense). 

I have tried taking Melatonin with some success but this past week I have not slept well which affects how I do during the day. I was wondering if anyone has any advice to either stay asleep or to help relieve the Paraesthesia.

Thanks so much!

ps. I have not been diagnosed with MS but my PCP believes that I have it and is sendind me to a neurologist who specializes in MS (appointment Oct 1st).

I get that too. And I've made it worse by daring to do too much yard work and stain a fence the last two weekends. Now I'm paying in a really painful way. I don't know why too much activity sets it off...I picture the muscles spasming and squeezing nerves that are already messed up. Anyway- I take a clonazepam to help with muscle spasms, sleep and a bit wit nerve pain. I'm in too much now so won't type much. I am diagnosed since 05. Neuro prescribed nortriptyline two months ago but I haven't started it yet. Lots of reasons, but I need to try it and something else if it doesn't help. I don't know if you aren ot diagnosed what you can get. Sorry. It is miserable and must be especially frustrating without a dx!
