I would just like to give a big shout out and THANK YOU to WebMD. Have you tried their symptom checker? It's great fun....especially if you have like muscle pain in your arm and want to see what is causing it, but then find out you could have one of the following:
median nerve injury
or, and this one is my FAVORITE:
Don't you think I would know if I burned my arm with a chemical or damaged my nerves?? All I really wanted to know was why my arm hurt. I was hoping they'd tell me which muscle I pulled.
SO, here is a BIG FAT THANK YOU to WebMD for SUCCESSFULLY and TOTALLY FREAKING ME OUT! It's a good thing I just went to the doctor and she told me my heart and lungs sounded fine, because when you search for heart burn you get a whole bunch of scary diseases!!
My best advice? If it keeps bugging you after a week, call the doctor. If it hurts enough to make you cry, go see the doctor ASAP. Of course, that's just me though.... to each his/her own!
