Had bilateral total knee replacement 7 weeks ago. Doctor suggested massaging the scar to help with sensitivity and said that I could use any lotion or cream. I have only used normal moisturizers so far. Sensitivity is improving but not fast enough to wear normal clothes yet without getting massively irritated. Is there anything that I can do to help with the sensitivity faster? What is the best lotion or cream for big scars? What will help with the tightness?
