Yesterday, I suddenly got severe stabbing pain in the right side of my chest. It isn't in the breast, or muscle. I've been sneezing the last several days, but every since I got this pain I cannot complete a sneeze (not that I want to sneeze, but when my body automatically starts to sneeze the searing pain halts the sneeze immediately).
The pain is worse if I bend over. I also discovered (accidentally) that there is a spot under my right arm, closer to my chest than to my back that increases the pain when I press on it.
I don't have any pain in the left side, sternum, or abdomen. I am not having any problems with breathing. Other than the sneezing, I am not having any respiratory problems. I do have some back pain that I cannot tell if it is related.
Does anyone have any idea what this might be caused by? I'm not concerned that it is anything serious, but would like to know what it is.
