Hi Dr,over the last few weeks i been doing a bit of gym to get fit as im putting lots of kilos since i gave birth to my srcong child via c s section.almost over 6 yrs now.over the last few weeks i dicided to go to the gym to get fit but i noticed i have brown spotting (private part)even a blood cloth but seems old blood blackish colour.i took few days 3days max.then my lower abdomen near where the cs section was been done 6 yrs ago,a bit painful thingling.so i stop excersicing for few days seems the spotting are getting better.im just wondering why im having those spots eventhugh i already finish my period a week ago before i hit the gym,also im experiencing difficlty of breathing.i am having a pain in my right shoulder blade due to physical work.but seems affecting my breathing too.when i inhale seems i dont get enough air so i have to sort of bending down to curve my back just to get more air but still not good enough and it a bit of pain in my shouder blade when i try to inhale a bit deeper.also seems like something blocking around my esupagus.need your moral support/advice.cheers .thnk you Dr.
