I have some symptoms you mention. It is difficult for me to sit. My legs have some burning, but it is more like creepy crawlies or mosquitoes on them. My pain PA told me to rub legs for two minutes twice a day to desensitize them.

I have some exercises a physical therapist gave me.

My pain is also in abs and side of waist.

I resigned myself to just keep moving around.

I am on gabapentin and lidoderm pain patch.
