Hi Sandra and Seabreeze,
These cramping episodes sound like carpo-pedal spasms, and are often due to low calcium levels (either regular serum calcium or ionized calcium) in the blood. The only reason that I am aware of this is because my endocrinologist totally expected me to have these specific spasms, based on my low parathyroid hormone level. Typically with hypoparathyoidism, it is the low calcium levels that cause the symptoms (such as carpo-pedal spasms). Turns out I don't have true hypoparathyroidism (my calcium is high normal), and my PTH is being blocked by something else.
Anyway, both of your descriptions sound exactly like what the endo described to me and showed me (with the claw-like involuntary cramping of the hands, wrists, fingers, ankles & toes). I don't have that and I don't have low calcium levels, but believe me, I researched calcium, Vitamin D, and PTH like crazy, and I got a lot of insight from a knowledgeable lab tech, as well as a physician.
Have either of you had your calcium levels checked lately? Ionized calcium isn't routinely drawn, but to me it sounds like both of your symptoms may warrant a further check into your calcium metabolism, including the ionized value. Having the Vitamin D level and PTH level done along with those would be extremely helpful as well. Vitamin D helps the body absorb calcium in the places it needs to go, so that might explain why Seabreeze is getting some improvement since being on the Vitamin D supplements.
The endo told me that the carpo-pedal spasms can be excruciatingly painful, so I hope you find out what is causing them and can get some relief. It sounds like a trip to the Dr. to get some bloodwork done may be in order. Make sure that you show them what your hands/fingers do when this happens, as apparently it is classic for low calcium levels. Sometimes the regular calcium level can be normal, but the ionized value is low: either one being low can cause the spasms. If the values get too low, it can lead to tetany (tightening spasms over much of the body) or even seizures.
Sandra--if you are getting spasms/cramping in your throat as well, please get this checked ASAP.
