<s>[INST] hi doctor. ma dad got accident day before yesterday.. he had a injury in left knee..we visited bone specialist,,he said 2 do ice compression for 3 days..... but swelling is increasing .. and he said the blood will be removed by surgery. is dis the right way 2 diagnose... Shouldn t there be heat given instead of ice compression. i think ice compression would lead to blood clotting,what should be done? [/INST] Hello, In early stages after injury ice or cold compresses are better & needed to decrease the swelling. Ice cools down the increased blood flow in affected area and decrease the swelling. I will not advise surgery just to remove blood clot inside knee. The minor blood clot in knee does resolve by itself. You may apply a compression bandage like Ace bandage for this & take second opinion. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
