thoracic 7 & 8 radiculopathy-burning & colon problems

I have a diagnosis of radiculopathy of T 7 &8., per MRI, He also said T4 was herniated, but that wasn't causing all my pain and problems only T 7, 8 were my big problems.My dr said theree were no disc left at 7,8. Degenerative disc disease. Problems" diahrea constantly, intense burning of lower 4 ribs on R side, loss of colon contol & cramping (R side), sore or HOT spots on R rib cage. A GI doctor did many test & said the spasms were caused by what he thought was the thoracic. He was correct. I've had an epidural, but it helped about 5% of 100%. Not enough. The thoracic 7-8 has been hurting more since I recieved the epidural 2 weeks ago. Is there anything else I can do? Should I come to see you?  Is there a certain dr of place that specializes in teh thoracic area? I cannot take this intense pain anymore- it is TOO INTENSE. PLEASE help. Who is the best place to help me? I think I am too young for a pain pump, but I will get it if I have to. Thank You so Much for Your Time, Lindy
