I've been experiencing some pretty difficult pain for quite some time in my calves. It is so painful, it sometimes takes my breath away. I guess the best way to explain what I feel is that perhaps my calves/muscles/tendons, maybe even tissue, I don't even know, pops out of place during a stretch! My reaction to it when it happens is to rub it profusely & can get what ever it is, back in place! It is painful as heck! Then, it is so hard to walk the next day, and I am fearful to have even a teency bit of a stretch in fear that it will happen again! It mostly occurs over night while I'm sleeping, but has happened during the day, and that's only because it happened prior that night. It occurs about once, or twice a month & have found usually after a day of being on my feet, from working, walking, or a physical activity from the day! Today my left foot & ankle is swollen, which is a new symptom after it happening last night. I have tried wrapping my calves in an ace bandage wrap trying to keep what ever it is coming apart, together! I am planning a doctor visit soon, but have been seeking info via the internet to see if I'm the only one experiencing this and what has been done to help! And so far, not one bit of luck! What is causing this? =(
