Hi, for the past 2 weeks or so I have had really uncomfortable pain in my ribs, just under where my bra sits, the pain has got worse and is really sharp, my ribs and top abdominal feel really tight, I keep going dizzy and light headed, I also have really bad back pain and breasts feel tight heavy and sore, I have headache and I thought I could have been pregnant, I had all of the symptoms but all negative pregnancy tests, I had some heavy blreding for 3/4 days which was shorter and different to a period, the pain in my ribs is causing me to be unable to get comfortable,and is effecting my upper back and shoulder, what could this be please? What should I do? Doctors are useless!
