Fracture of (r) radial head (c) 8 wks. above elbow still red, inflamed, sore, warm to touch stiff joint. normal recovery or cause for concern?

The question lacks-: -description of the fracture as well as the treatment. It can vary from non-displaced to displaced, 1 fragment or many. Treatment can be from sling 2 surgery. Need more information.

Hard to know: The orthopedist/physician that has seen you previously and that has performed physical examination will know better; but infection of the joint or misalignment would need to be considered. Perhaps more likely that this is normal progression of healing (depending on severity of findings you mention). Have it checked out to be sure.
