Yesterday I operated on a patient who had severe pain and electric current-like sensations in the distal limb beyond the knee joint. I was suspecting entrapment of the peroneal nerve at knee level, as he had undergone a biopsy procedure at the same site and had a scar. A biopsy was done for confirmation of chondromatosis knee joint, which he still has. Now after about 24 hours, he is complaining of severe pain and all other symptoms. What should I do now?
