I am a healthy 62 year old woman.  I lifted a box 2 days ago which was too heavy and felt like I tore something in my abdomen...it burned a little and has been achy since.  I have also felt unusually tired since this happened.  It is possible that I am bleeding in that area?
Hi. Yes, this is definitely a muscle strain with minimal bleeding, which continues with pain. Another possibility is starting a hernia, which a Surgeon would be in a position to diagnose better-have you got a bulge at the spot of pain ?
