The plate and 14 screws provided my non union clav with strength and stability, but the pain is as bad or worse than before surgery, That's one year from surgery. Mislocated shooting tingling nerve pain on 8 inches of skin, and deep tissue pain, probably from the screws sticking though the bone, which remarkably is the normal way its done. In 50 years this will be considered barbaric. But it's strong.
Your body/nerves are reliving the surgery. Try 200mg of Naperson OTC.
As soon as your doctor let you get the plate and screws removed you’ll feel like a new person.
