My dad had a partial kidney removed just before Christmas, 2009. The cancer was contained in the kidney and the surgery was a success; however, he is still having difficulty recovering. He is 72 years old, but in great shape. It has been 4 months now and he still has an intense burning around the incision, with swelling and tightness. He also complains of a salty taste in his mouth and sometimes it is a metallic taste in his mouth. He just had another series of tests run including CT Scan and the report indicated that everything looks good. Can anyone provide any advice on things he might can try to help with his symptoms? Thanks in advance for any guidance you can provide.
