In january 2020 I fell on the road and got my arm and leg injured. Now after 10 months arm got healed completely which was a rash but the there was wound with cut which was treated with medication and dressing, no stitches but now I i observed that some part of the wound is brown and some part light pink and it didn't heal properly and from few weeks I noticed that when I stand for 1-2 min the skin around wound started itching heavily it only happens when I am standing at a place but not walking or sitting and its turning to light brown. I do not have any other issues previously last month I got liver test and complete blood picture and ultra sound as I got fever and stomach pain and it was acidity problem nothing else after post covid. I do not know why my wound is itching while standing and its brown in some parts inside. Is there any problem or part of healing process?
