i have a sharp pain on my lower right ribs. it went away for about 4 days but...

[Shady]

...came back when i woke up? i started to feel the pain at work but it was minor so i kept working. after a few days the pain increased and when i woke up to go to work i stretched and felt a pop. the pain was so intense i could not move, breathe, walk, or even talk without it hurting. 4 days after that the pain was gone and stayed gone for about 3 days. it felt perfectly fine last night but when i woke up this morning i had the sharp pain back. i dont know if its an out of place rib, or if its something more serious.. i went to the doctor 3 times and he told me it was just a torn muscle, but i believe its something different
