Endoscopy #3 coming soon!

So i was in the ER once again rushed by ambulance because i was weak on my feet and felt like i was going to pass out. My stomach was also killing me!!! I have a peptic ulcer that was diagnosed in Oct 2013. Well i get there and my respiratory rate and bp were periodically dropping. Then they had me check bp in different positions including standing and was told me blood pressure/RR dropped when i stood up so the doctor said i was dehydrated. I am 10 months out this sucks and is getting really old already. I got stuck twice in the ambulance for an IV with no luck then another 1x in the ER before actually getting an iv in. Also got stuck twice to find a vein for blood work.. just wondering when it will all end. Now i have another endoscopy scheduled for Jan 28th to check on what is going on with my ulcer. Frustration is setting in again.....My labs were perfect though so that's good.
