Welcome to ThisIsMS, blackstone. You are correct – no one can diagnose you via this website.
I encourage you to find a GP or internist who wants to be a "disease detective." You have definite symptoms; there is a cause at the root of these symptoms. You need a partnership with a good medical professional.
Since you want "to hear some opinions from members," I offer mine: I suggest that you ask your physician to order a "fasting blood insulin test" (NOT to be confused with a simple glucose test). The optimal result should be 3 UU/ML or lower. Excess insulin thickens and stiffens the muscles and leads to insulin resistance. Muscles are certainly involved in bladder and bowel problems; they can certainly be involved in your other symptoms. All the best to you
My hypothesis: excess insulin (hyperinsulinemia) plays a major role in MS, as developed in my initial post: http://www.thisisms.com/forum/general-discussion-f1/topic1878.html "Insulin – Could This Be the Key?"
