my sister lives in Texas and it has been really hot there, she is having problems with swelling in her ankles, told me this evening her ankles feels really tight and that she isn t having any other problems else where..she not sure what to do. My sister is 58 and I don t know her weight, but my guess she might be around 220lbs, she has asthma, glucoma, has had part of her stomach removed to help her loose weight a few years back.
