Hello, I m a 47 year old female. For the past year or so I have noticed that my feet and ankles tend to swell as soon as the hot weather and humidity arrive. The swelling pops up in the evening and is gone in the morning. I do have high blood pressure and am taking abeta blocker. Could the swelling be an effect of the medication? I also noticied significant swelling after a long plane ride, which dissappeared after a day. Why am I swelling during the heat and plane rides? I am also in perimenopause and blood work shows a homononal balance.
