Hello and welcome to Healthcare Magic. Thanks for your query.
The redness, warmth and tenderness on your knee is indicative of an infection. It needs to be determined whether it is a superficial infection of the skin / soft tissue
or an underlying infection / inflamation of the knee joint. I would advise you to have a proper physical examination done to ascertain this, in order to plan further treatment. Certain medical conditions like diabetes
, nutritional deficiency
, immune deficiency
, ec. can cause recurrent infections. So, you need to have this checked also.
