I did and he was completely useless, he prescribed me baclofen which I take like tictacs and they do jack shit. He was out of ideas so I googled it and found out about magnesium. Got some "Calm" which is magnesium citrate and no more insane pain.
Supplementing magnesium can help lots of people since it is lacking in many people's diets. It can also help you get more and better sleep, just avoid magnesium oxide, that will just make you poop and is unfortunately the form used in many supplements and multi vitamins.
Also check out NuSalt, it's a salt substitute that is pure potassium. Way cheaper than supplements, my local grocery store sells a container for under $2.
