Rt side pain mid level back / chest

[8ball]

Three days ago, I was having some pain in the middle right side of my back.  I was beginning to get a cold/flu so attributed it to bodyaches, but two nights ago while in bed there was a sharp knifelike pain in that spot when turning over.  It was so severe it caused me to catch my breath.  I got up took some ibuprofen and the pain subsided until I lay back down.  I had a very difficult time trying to find a comfortable position.  At work yesterday, the pain seemed to migrate around to the front, still on the right side, it was not too intense and I went to bed.  The pain was manageable until early this morning, (4:00 am), I was lying on my left side and started to turn over when there was the sharp pain in the front/middle right side of my chest.  I went to push myself up with my right arm, and there was a tearing sensation in my chest that knocked me back on the bed.  Any thoughts would be appreciated.
P.S.  There is also discomfort front and back when I inhale too deeply.

What you have experienced suggests that there is either a musculoskeletal problem, such as a fractured rib or strain of the muscles and ligaments that connect the ribs.  An even more likely possibility, if you can recall no chest trauma, is a spontaneous pneumothorax, with a collapse of your lung and pleurisy.  If you have not already done so, you should be examined by a doctor and have a chest x-ray.  If the lung has collapsed, you may need to have a small tube placed in your chest to suck out the air.

You should not delay.
