In response to hopeful2:

To answer your question about Raynaud's. As a slender woman, now seriously underweight (unknown cause), I experienced Raynaud's in my fingertips when hiking in the cold as a young person. Now in my late 70's, it occurs daily - not necessarily because my hands are cold. Unfortunately it no longer easily responds to my wiggling fingers or aplying heat and rubbing until it relents an hour later. I never correlated it to my redundant colon that I think is mostly inherited and then is exacerbated by strain bms that caused my inguinal hernia.

Sorry if this is tmi. If you find a correction with Raynauds vascular malfunction and tortuous colon, please share.
