[|Human|] I went to the ER on Monday and they did a Cat Scan , blood work and an EKG and said I am ok but I still feel numb on my left side. I had a knee replaced in Dec 2nd so have appt with orthopedic surgeon on Thursday but don t know why i feel funny on the left side.
[|AI|]  Hithank-you for providing the brief history of you. A thorough clinical examination is advised. As you had knee replacement, we should understand that there will be changes in the gait mechanism pre knee replacement and post knee replacement there will be a different gait mechanism due to which there will be some nerve impingement in the lumbar spine and needs a thorough clinical examination. Due to this there will be pain, numbness and tiling in the legs and with physical therapy these symptoms can be corrected.in my clinical practice most cases have sucChatDoctorplaints and with physical therapy they respond well.
