Poor Lukey had this ganglion cyst for several years. It didn't bother him until now. He said it caused decrease range of motion and some pain with extension. We went to a German Orthopaedic doctor (the same one that worked with me and my lateral epicondylitis/ tennis elbow) and after an MRI, he cut it out.
Luke was so brave. He was pretty funny/drowsy coming out of anesthesia.
He did several weeks of physical therapy to recover his range of motion.
