A herniated disk can irritate nearby nerves and result in pain, numbness or weakness in an arm or leg.
Unfortunately, this isn't something that has a quick fix.
Treatments include medications such as narcotics, nerve pain medications, muscle relaxers, and cortisone injections. Other methods to promote comfort include therapies such as hot/cold therapy, electrical stimulation, and certain exercises.
If none of these methods help with your pain, then surgery may be an option. This is best left to discuss with your doctor.
Wishing you the best,
