Hello,
Swelling in one leg and one hand for 2–3 days can be due to fluid retention, vein/lymph blockage, infection, or sometimes heart/
kidney issues. The exact reason cannot be confirmed without examination and a few tests, so it’s important to get evaluated soon.
I hope it helps you. If more questions are in your mind, you can reach me for a free detailed consultation on WhatsApp at nine one one nine two five five six nine nine.
