I discovered a hard lump in my muscle abdomen and now i am totally panicking after a quick google search. During my pregnancy 2nyears ago, the baby was kicking so hard in my ribs and muscle that for couple of months I couldn't even bend because of the muscle and rib pain. Now after 2 years it feels like a hard lump in my muscle exactly where he used to kick. I also started exercising more and working on my core everyday and not sure if it influenced this or not. I've made a GP appointment but my anxiety is trough the roof that this could be something serious like cancer.
