My knuckle (index finger & thumb) are bruised swollen & warm to the touch along with my knee cap and wrist bone. All of this has happened suddenly and without trauma to these areas. The knuckle happened when I barely knocked it grabbing a handle. I also have popped blood vessels on the palms of my hands.
Hello, It could be a local inflammation. As of now, you can use analgesics/anti-inflammatory combination like diclofenac/serratiopeptidase for symptomatic relief.  If symptoms persist better to consult an orthopedic and get evaluated. An MRI scan might be required for further assessment. Hope I have answered your query. Let me know if I can assist you further.
