In a lot of cases it will show if a nerve's being compressed. As far as how long it will take to get better, it really depends on how bad it is.
The 1st step is generally medication and Physical Therapy, which often does help. Surgery is usually the last resort.
Do you know if I do the MRI...... If it shows I pulled a nerve.... How long will it be until it's better? And what do I do for it to heal?
As far as stress pain cycle, ime pain causes stress, and stress causes pain.
