Appetite

hi all, i have a question and wonder if anyone else has the same problem. in 2012 i had what would be the first of 3 endescooies over the past 6 years fairly routine procedure where they found h/pyrol in the first and barrets oesaphagus after the 2nd endescooy for which i am on ppi meds in lanszoprozole 30 mg @ day. over the past 12 mthx or so i notice my muscle joints in my elbows have become vert sore and tender. some say lanszoprozole could cause this. however, my main enquiry is that after the 3rd endescopy i felt different in that was like a hole in my tummy? i remember when the tube was inserted down my throat into my stomach i felt a chocking sensation and sonething not right in my tummy. it was only after that test i lost my apoetite where as after the two previous endescopies i was fine and back to normal after a day or 2 and back to my usual appetite. i just wonder if anyone elsd had a similar experience ? it feels like they maybe took too much for the test compared ti the first 2 endescopies. any ideas guys?
