Hello and welcome to justanswer!
Can you please elaborate your problem that what exactly is your problem?
Why are concerned about a pinched nerve?
Thank you very much for your kind input.
The answer to your question is YES .Actually the nerve connections controlling the the function of the muscles of LES ( Lower esophageal sphincter ) come partly from T1-T4 and partly from the upper thoracic spine.So once there is trauma ,or the nerve in that region is pinched or severed , the control of the LES is gone , hence no contraction of LES and the gastric contents go up i the esophagus causing GERD like symptoms.The same lower connections are concerned with pain back accompanied by pain in the stomach, so anybody having pain in the back also complains of pain back.You need to consult a group of orthopedist , neurophysician and an internist to improve your symptoms .But until than you can take Nexium 40 mg , Motilium 10 mg 3 times a day , Tab Neurotin 100 mg once a day, to relive your symptoms to some extent.You also need to do an MRI of your neck and middle spine to exactly locate your problem.
Best of luck.
Hope i have answered your question.
