It happened right after i was eating dinner one night when i stood up i had a blunt pain in my chest. When i took a deep breath, it would hurt even more. But when i sat down i was fine. After that night, my breathing's been a bit more difficult, or maybe i'm just over thinking things. This pain happened again the next night, a pain in my upper right abdominal area, under the right boob and another sharp pain in my chest. Again, deep breaths made things worse..but it only lasts 10-15 seconds. The night after THAT, my chest didn't hurt, but the breathing is still a bit difficult and my right boob began having this random pulsating pain that would only last for about 10 seconds...on and off... then i had a headache on the right side of my temporal lobe. Not the whole head...just that side...that one area. 10 seconds...on and off...then it would switch over the the left side of my head...then the left boob. I'm not sure what this is...Could you please help explain it to me?
