Sounds like neuropathy pain, the burning....I get it down both of my legs. Tell you doctor and let them help you as it is an awful feeling.

I get it, I'll look to see if my phone caught on fire or something but no its just a random burning sensation

Yes I do mine are drunk legs to where they want too.

I get that feeling all the time but it coincides wjth what i call bicycle legs. They just ache constantly like ive been on a bike ride

I do get the burning sensations as well as a numbness feeling and have been told by my Neurologist that I have nerve damage in my lower back and in my neck. The cause is from bulging discs and bone spurs pinching nerves. So far the damage is minor and treating it with with a nerve blocker has been helping although some times the feelings sneak through. Every couple years the Doc does nerve tests to track any changes. We are waiting to do any surgery because the risk is so high.
