To JeanThanks for the interest. My MD who is a clinical nutrionist calls my foot pain a nutritional deficiency because it does improve when I gain weight. I don't have any specific deficiencies that he can find. The problem is getting enough calories down without turning into a constipated, bloated lump. I eat lots of small meals, turkey, avocado, vegetables, fibre, moderate amounts of mayo and oils (for calories) and drink a liquid supplement at night. I just can't get enough in to boost my weight. I'm 5'9" and 135 lbs, which makes me skinny, but not clinically malnourished. (I did have an IV at a lower weight) I have a good appetite. Within the last few years (i've had IBS 10 yrs) my feet have become sensitive to anything more than a short walk. It's weird, just what I need, another weird symptom. So I'm thinking of pursuing a tilt table test for neurally mediated hypotension. Anyway thanks for listening.
