I Am Recovering From Shoulder Replacement Surgery And I Am

I am recovering from shoulder replacement surgery and I am on a small dose of generac mobic. I tried to get off but it's still too,painful for me to do the excerises. It has raised my A1C and cholesterol and gives me heartburn. I take a pepsid when needed. What are these drugs doing long term? Hate to be on anything. I am 72. Do not eat meat, fried foods or smoke or drink.never have.
