Hello Doctor, My husband has undergone Testicular Biopsy day before yesterday. He had pains on his left side lower abdomen after that.. They gave Tremadol injection.. last night he had severe pain in his left side lower abdomen.. That is the joint to his left leg. He said left leg is paining and not able to walk. Could that be because of the way that injection was given or because of the biopsy that was done. Kindly advice.. What medicine can I use to reduce his pain..
