Hi, my feet and calves mostly, but also thighs, have been having tingling and muscle cramping. The muscle cramping has been at night when i am laying down in bed, but the feet tingling is there all the time now.....this all pretty much started a month ago. That night i had very severe and painful gripping muscle cramps in both my feet and both legs from the tip of my foot to the very top of my thigh.....i was crying out in agony for hours, then for two days i could barely walk. That episode subsided but since that night about a month ago, i have had this tingling in my feet-and calves lesser-, and at frequently muscle cramping in the feet, calf and thigh......ive been living at a sulphur hot springs and have been going into the pool probably close to daily-would this have something to do with it? Iam a 68 yr old female......thank you!
