[|Human|] hi my dad had a liver transplant 4weeks ago and today has got a large purple bruise on his left thigh down to his calf. hehasnt knocked it that hes aware of but we dont know where its come from? he also has been suffering from swollen legs up to the knee just recently
[|AI|]  Hello, As post any surgery this is some post-surgery effects and needs nothing to worry much. Swelling in the legs is due to lack of venous return. And with using the stocking and keeping the leg elevated over a pillow with doing some simple ankle toe movements the swelling will come down. Taking the bruise into consideration it will go on its own without any kind of worry. As mentioned earlier post surgery there is some temporary effect and which will resolve with the time. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
