<s>[INST] Hello , if had total hip replacement in Feb 2016 , due to a disease, how when I stay on my feet for a while, the left leg just above my ankle swells and turns very red, and becomes very painful could this have anything to do with my replacement?? If not what could be , I have been diagnosed with fibromyalgia in last few months also . [/INST] HI I UNDERWENT YOUR QUESTIONING MY OPINION YES LEG SWELLING COULD BE A POSSIBILITY AFTER TOTAL HIP REPLACEMENT.IF YOU ARE NOT MOBILE AFTER SURGERY AND PRONE TO RISK FACTORS, YOU MIGHT HAVE A THROMBOSIS IN LEG.PAIN AND SWELLING IN LEG CAN BE A FEATURE OF THROMBOSIS ALSO LEG COULD NORMALLY SWELL AFTER SURGERY FOR A YEAR OR SO.PLEASE DO VISIT YOUR OPERATING SURGEON SO THAT HE CAN Assess YOU AND GUIDE YOU APPROPRIATELY.WISHING YOU BEST OF LUCK </s>
