I'd see your primary care doctor first and have him/her refer you to the correct specialty.
I am confused if i have to consult orthopedic doctor or a neurologist.
I would try and find out what's happening, especially since the pain is constant, and lasts for over a week at a time when it does "flare up". I would make an appointment with your doctor and just go from there. I wonder if you should wait for the next pain "flare up" and see your doctor then? I guess it depends on whether or not you can see your doctor right away or not. Again, I would certainly try and "get to the bottom of it". Good luck,
