First off. I'm making an appointment with my doctor. I'm kind of hoping for some opinions and possibly some other things I should think to tell her about when I see her. Following are the symptoms I'm having:

Tingling and tenderness on my right side, about midway up my torso. It has been going on for about 3 days now.

Numbness in my right hand. It happens once or twice a day, I get feeling back (Along with pins and needles) after a few minutes. This has been going on for a few weeks.

Light headed when I stand up. Mostly like being drunk, happens once or twice a day, has been going on for a few weeks.

Recent medical history:

I take Naproxyn and Ibuprofen for my back. About a month ago I was taking antibiotics for a pretty nasty infection in my left heel. I'm a little bit overweight, 32 years old, smoke about a pack every two days, otherwise am in good health.

Anything else I should tell my doctor? Any ideas what might be going on? I know the more I can tell her the easier it is for her to help me.

It could be something to do with the meds. Or you could have a pinched nerve or something or you could be lacking some vitamin(s).
You might want to try taking B complex (especially B12, folic acid & thiamin) and flaxseed oil it can't hurt.
