Definitely you need to see a gastrologist. I did when all of those things started with the exception of the constipation as I have chronic diarrhea and found that I have colitis so I really have to watch everything I eat and take lots of probiotics best of luck to you.

The medicine I take for the spasms is Librax twice a day.

I have bloating but that came from a blocked urethan tube and bypassed the bladder and filled my body instead. I'm trying to get rid of it and I will soon.

It can be difficult...Ive been doing alot better lately...I have IBS/constipation and need to be very careful what I eat. Dairy is the worst on me. I take magnesium daily at 400mgs. I try to drink alot more water and I only eat very small amounts of food throughout the day. It was a pain at first but it has helped. Best to you as you try to figure out what works best for you.

I have GERD, which is very similar to your symptoms. I recommend asking for a referral to a Gastroenterologist to sort out the causes and treatment of your discomfort.
