Hi..I was just prescribed CHOLESTYRAMINE powder...by my primary doctor. I am very ill with chronic pain in my rib cage and nerve pain shooting down both legs..i have gained much wait in the past few months. i get epidurals frequently by my pain doctor. I will be seeing a neurologist on monday, the doctors suspect muscular sclerosis plus i have gall stones...i am so sad that it feels like i will never get away from this vertigo, nausea and this pain is so awful..i dont know what this new med is for..i do have copd due to my costrocondritis and need help to care for my physical needs..i guess i am concerned about the side efffects that i might experience with this mdicine and what is it for? Thank you and God bless.
