I have a bad case of pinched nerves in my left side of the back and the pain goes down the leg into the foot and it is excruciating and I cannot walk, sit, or lay down. They have tried epidurals, rhizotomy or blocking the nerves. Nothing touches the pain...Tylenol, trammadol, melixacam, hydrocodone, diazipan, Today, they gave me gabapentin and it is not helping at all. Can I try taking vialium or another pain pill along with the gabapentin?
