My father-in-law had a partial knee replacement and after the surgery, he was given an injection to block the pain. Since then he had fallen or almost fallen four times because his leg gives out and he loses his control of it. He also experiences redness in the knee area even though the scar healed property and a burning painful sensation. Is this due to the nerve block injection and what can I do to get better to him...he had been going to therapy for the knee and gone back several times to the surgeon due to the loss of control. He has good movement after the surgery and therapist cannot understand why it so swelled What can I do him?
Please suggest me an affordable orthopedic doctor near my area.
