Yes, definitely see a doctor. Phantom pains, throbbing and other odd feelings are very common when quitting, so this is probably just how it's manifesting itself for you, but you should still see someone to be sure.
But Idaho is right. Two weeks on your own is very impressive, but the fact that you found this site tells me that you are looking for some kind of help.
No shame in that, we're all here for that reason. Getting connected with the groups here gives you access to a network of people who are all going through the same thing. It's a group where you can bounce ideas around, discuss symptoms and strategies for dealing with things. Also a good place to blow off steam. Additionally, it's about accountability. You have to commit to it to benefit, but I'm telling you it's worth it.
Regardless of your health situation, you need to stay quit. Hang around here and your chances will greatly increase towards that end.
