Healthgrades Editorial Staff. Tingling in both feet can have a number of causes, including an injury, sitting in one position for a long period of time, or a circulation problem that impairs blood flow to the feet. Tingling in both feet can also be caused by nerve damage from extreme heat or cold or from toxic substances.
A lopped-off finger will still have a place on your hand for about 12 hours after amputation if not refrigerated, but a full limb like an arm or leg -- left at room temperature -- must be reattached within six to 12 hours, due to rapid death of muscle tissue.
Recovery time after surgery varies, depending on the procedure you have. When the shoulder tendon is simply released and not reattached, recovery is almost immediate. There are usually no restrictions on activity following that type of surgery. When the tendon is reattached to the bone, healing takes about three months. Patients should not lift anything heavy for about six weeks after surgery. Manual labor, sports and other physical activities that involve your arm may be limited for another six weeks.
