Hi helpmepls.
After reading ur description, i know exactly how u feel. It reminds of my partner who is also 30, hes been exactly in ur situation, went to a&e several times, all they said nothing wrong with him, said he needs to relax but the pain still there, its been hell. that happened 2 half yrs ago, he still suffers now but less cos hes on omperazole 40mg and was told he has to take it for life. urs sounds like Acid Reflux and need to tell ur gp to refer u to gastroenterologist to check it out. May i ask does the pain worse when ur lifting heavy stuff and sneeze?
