Sorry you're suffering so much. It does usually take a little time to get a correct diagnosis so hang in there! Hair loss could be a lot of things like stress, hormones even some medications can cause it. My mom has Osteoarthritis and has very bad pain. You need to keep checking your calcium levels as it's easier to get osteoporosis. Have you ever had any upper or lower scopes? I had my first upper scope a year ago and there were all of my problems! Chronic gastritis. But I'm still working that out! Xanax is short lived, so kind of a weird one I would pick to help with sleep. What else have you tried for sleep? I would suggest trying different avenues for sleep. Maybe a sleep study would shed some light and it would be good to rule out sleep apnea.
