My left ankle is very swollen and red/tender on the outside. A little itchy, no nagging pain, but hurts if I move it. It felt like a sprain on Tuesday and I don t recall twisting it. I was working in a dusty garage and attic that day. It has become more swollen each day, and there s more redness. it s warm, not hot, and I don t feel like I have a fever. Will an antihistamine help if it s an insect bite? I ve been trying to keep it elevated and on ice, but I know I m not doing that nearly enough. Too much to do!
