Traumatic Bursitis and Lancing

Patient: I had a fall and needed stitches in my knee. There was normal swelling and yellow bruising, but now after the stitches are out, the surrounding knee area below and to the inside of the leg is tingly and almost numb. I saw a doctor who bandaged it up and told me to take NSAIDs. 5 weeks later, there is no improvement. Does it need lancing? If so what is invovled and is it painful (as I am very prone to severe panic attacks).

Doctor:
