I Have Excessive Abdominal Movement With No Pain, Just Terribly

I have excessive abdominal movement with no pain, just terribly annoying. I am 63 and have been in a wheel chair for almost 5 years. I do have anxiety, and excessive salvia and swallowing which is putting foam in my stomach. A lot of pain and gums and jaws hurt constantly; was from clenching my teeth but I constantly try not to clench teeth. Take medications for high blood pressure, diabetes, bipolar and prilecet for stomach.
