<s>[INST] I had laproscopic gallbladder removal surgery yesterday. I ve noticed, today, that both of my upper arms are warm and red. I haven t been rubbing them but the temperature difference is pretty significant. They are not tender to touch, no pain at all, but they are warmer than the rest of my body and quite red. Should I be concerned? [/INST] Dear madam, usually after laparoscopic surgeries TH increased level of air in abdomen can cause shoulder pain, especially the left one because of irritated Phoenix nerve. But skin redness and warmness aren't usually sign of it. It can be caused by skin infection or allergy or by joint inflammation. So you should do inflammatory markers and shoulder RTG if you are worried about it. Wish you good health,  </s>
