I Am Overweight Woman. 54 Years Old. I Have Been

I am overweight woman. 54 years old. I have been having problems with both legs and swollen tops of feet I feel like water build up I have asthma and have a hard time telling the difference if its asthma and use my pump and then it could be water building up. Both legs are tight reddish and itchy and swollen esp. the ankles on both legs. I feel on 12/9 over a tree stump and hit the concrete ground pretty hard, but I got up and didnt go get it checked out. I take daily medication for heart, water, blood pressure.
