Hey, gma45 - It sounds like you could have a very serious medical condition. PLEASE SEE AN MD ASAP. It is not worth the risk even if cash is short. If you have no money, go the to nearest emergency room. It is possible that you could have a blood clot in your leg. If that clot moves to your chest area it is extremely dangerous. It could also be congestive heart failure. Do you get any exercise at all? If not please start walking 1 mile a day (build your stamina up gradually) to get your blood flowing. Do you take a QD81 aspirin each day? If not, please start. Good luck (and health) to you.
