Pain In Back, Clear Ulcer Pain and Chest pain

After a year of dealing with this I thought id try here and see if anyone had similar experiences. I am about 8 years post surgery. I have had horrible spastic pain in my high upper left back side. It is beyond horrible on the pain scale. To me it seems similar to when I had gallbladder pains (which was removed 4 months post op). We tried regular anti spasmics drugs but doctor thought it was more my stomach. It took 3 months to see a GI doctor who thought it was muscular. I landed in the ER with chest pains that worried me only to hear I should suck up the pain and they just called it gastris. I got charged 6k to swallow some maalox and liquid lidocaine. I am still waiting 2 months for endoscopy (last one was about 6 years ago when I had ulcers). It seems to be triggered after eating certain things. I will often find the only thing that can calm it is hot noodle Soup. I do have clear ulcer pains from time to time on top of the other 2 issues. While Im waiting for the endoscopy I was given more liquid lidocaine to try and see if it would help. I have mixed results with it. Overall Id say its innefective. I also was newly prescribed Robaxin for a back spasm and surprised that doesn't seem to touch it so Im leaning toward stomach. I am desperate to be rid of the pain and better yet get diagnosed and fixed before my next deductible year comes around.
