I had outside thigh lipo 2 and a half years ago. All went fine, but i've noticed in the last year that my upper thigh, lower buttocks skin is painful - almost like a sunburn - to the touch in the early morning before waking and for a while immediately after. It's almost like a bad sunburn. There are no markings, sores, etc., but it 'feels' like there should be. It gets very annoying and painful to the touch. Help?
