Whoa! First, if your cast is pushing on your calf, you should contact your doctor and see if this should be remedied. Second, try to hang on. It does get better. Although it took a while for the fog to clear after the shock, the anesthesia, etc., it got easier as I talked to people who supported me and prayed with and for me. Although You will feel bad, grieve, and be angry, just try to make yourself stay calm. Keep mending.
