Vinnie here, i too had Hodgkins 3B area infected was my abdomen, went for 6 mos of ABVD, now in remission, had it for a year, during the later stage had problems swallowing, had squeezing pain between my shoulder blades. After chemo therapy went for a myotomy test was diagnosed with Achalasia-diffuse esophageal spasms, pain in the upper back was GERD, so they say.Had 2 Bo-tox procedures, little improvement, having doubts about balloon dilation. My diagnosis, the lymphoma infitrated into the myenteric plexus, thus degenerating the ganglion cells. Now have chronic lung-scarring from the bleomycin-Cheers Vinnie
