Don't jump to the conclusion it's a damaged ulnar nerve and that you need potential career ending surgery. My 18-year-old son had EXACTLY your symptoms 2 years post-T. John 3 weeks ago. Talked to his surgeon. Figured he was done forever. Maybe re-routing the ulnar nerve so it wouldn't hurt in living his regular life.
Kid went to Dr. Marko Borba in Napa to do nerve testing to see the damage to the nerve. If he'd gone to most any other doctor for the nerve test...they wouldn't have done ultrasound on the elbow and they wouldn't have found...
The screw implanted in his elbow to hold the ulnar ligament in place 2 years ago is stick 3 mm above the bone in his elbow and the ulnar ligament rubs against the screw!
The surgeon can simply shave down the screw or totally remove it. The screw is useless. His ligament is attached fine now.
Dr. Borba said he's NEVER heard of a Tommy John patient with the symptoms be diagnosed...i.e., that the screw had moved and was hitting the ulnar nerve. Dr. Borba said, "I lecture internationally. I've never heard of anyone even considering the ulnar nerve symptoms stemming from the screw sticking out. It could be a real breakthrough because lots of pitchers have these symptoms."
So, my son went from thinking he was done pitching forever to Dr. Borba saying, "We can fix him. We just need to shave the screw down or remove it. It serves no purpose in there now."
Here's the key: Borba and his assistant used state-of-the-art ultrasound equipment to look at my son's ulnar nerve. Almost no doctor would use ultrasound! They'd assume what readers here assumed...ulnar nerve compressed, re-route the nerve, etc.
The assistant saw "something that looked like a piece of metal" in my son's elbow. She went to Dr. Borba who studied the ultrasound, found the screw and called my son back to his office!!!
He spent 90 minutes patiently looking for that screw via ultrasound and then seeing when and were it hit the nerve. He manipulated my son's elbow and...when my kid felt that terrible pain...the doctor spotted the screw and did what he does and took x-rays. The x-rays show the screw sticking up 3 mm and the ultra sound shows the ulnar nerve rubbing against it.
I don't know the odds of this being the case for others. I just know an interational lecturer said it could be a breakthrough. So...specifically ask you doctors to CHECK to see if that screw's in place. You're paying THEM.
If you need to have your doctor talk to Dr. Borba...email
