It would be good to see a neurologist to better find out what is going on and possibly to get some meds. In the meantime you could try a magnesium lotion on the areas that are tingling, burning etc. There are many available on Amazon. I use the lotion by Life-Flo as it is hypoallergenic and my sensitive skin does not mind it. The lotion helps me a lot. Also things that have helped me are getting out of bed and walking around barefoot on the carpet for 5 or 10 minutes, or using a foot massager for 10 minutes. There are supplements that can help and prescription meds but IMHO it would be good to talk with a doctor about what is safe to take or not. This web group also has a lot of posts on what to do and/or use at night, as unfortunately the tingling and burning at night, with lack of sleep, seems to be pretty.
universal. In my case I use the magnesium lotion at night and take Rx gabapentin only at night.
