I had arthroscopic surgery on my knee 2weeks ago and now have a bruise going up from my knee to my groin, and experiencing painful feeling when I lift my leg, there is also a red rash on my inner thigh that itches on part of the bruising... What could this be.  Also somewhat sensitive to touch.
Hi, As you have already undergone surgery, but now you have bruising and swelling, it may be due to edema. Kindly consult with your surgeon, you may require MRI to be knee joint. Treatment mainly depends upon the underlying condition.  For pain, you can take tablet Diclofenac and apply Diclofenac gel or ointment. Do warm fomentation.  Hope I have answered your query. Let me know if I can assist you further.
