My right side ankle is always painful when i send my eldest daughter to school , its like a 10 min walk tgt with travel back home. But it started to be in pain like after 5 mins . And my hand is swelling bad too 😭 its my 4th pregnancy and i finally have a babyboy after 3 girls , and the swelling plus ankle happens to me for the first time . Any home treatment i can do?
