Thank you for getting back to me at DoctorSpring.com.
Its really strange that if previous MRI is showing multiple lesions & in a single present MRI there are no lesions.You should ask your radiologist to review MRI results again.
The present pain at screw region can be due to friction between screw & biceps.nThis can also be confirmed by MRI.
At present you may take a good anti inflammatory analgesic like ultracet.This will help you.
Hope this helps, would be glad to discuss further. Regards
