what could this be?

Yesterday I woke up and was having some pain in my throat down by my collar bones (inside).  I have been burping a lot and when I do it hur ts a little.  It almost feels like when you swallow a huge gulp of water and your throat hurts because it almost got stuck.  Right now it only hurts when I feel gas build up and I burp.  Yesterday I ate every few hours a little bit at a time and by dinner I couldn't really eat a lot.  I have not eaten anything yet today because I don't want it to hurt.  What could I have done?  Oh and I am 8 months out.  I have not eaten or drank anything out of the ordinary in the last few days either. 

This is not something I am familiar with. I would contact your Dr's office.

Burping may be a sign of gall bladder trouble.  Please call your doctor.
