I truly hope you are under the care of a physician for this problem, when i say under care, i mean have routine follow up visits.
If you are in pain, especially nerve pain
this should be brought to the attention of your doctor, orthopedist to be exact (bone doctor).
There are many pain medications that can help alleviate your pain, as well as medications that are specifically designed to relieve nerve pain. Regardless, you will need a prescription from your doctor. If you can't get in to see your doctor, you can go to an urgent care
