I believe this is an injury which was caused by doing too many situps after not doing those exercises for a while. It wasn't immediate, but maybe days or a week after. It feels like it is right below the tip of the bottom of my left ribs. But it extends at times down my abdomen (basically hugging the abs...almost like there is a tendon there). I can pinpoint it, but when pressed, there is no pain. I have tried to 'find' a spot where I can press to produce pain or the ache, but cannot. So it does not feel 'on the surface'. Movement doesn't seem to necessarily cause any issues, but if I am standing or walking for a very long time, I can feel the ache more (almost like it is stressed). Or if I lean/stretch a certain way, I can feel also. Does not wake up during sleep. I am having some lower back pain now, but I don't think that is related. So, it feels like maybe obliques?
My concern is that it may be colon cancer, or something like that. But x-ray (regular) showed nothing (they said I was 'constipated', but I am not, and go regularly). Going for ultrasound this month. Had CT w/contrast about two years ago, and everything showed fine in the abdomen with no visible issues (this was not a virtual colonoscopy, just CT of the abdomen). No blood in stools. No apparent bowl changes and everything seems 'normal' to me besides this chronic ache.
Should it take this long to heal if it is muscle related? Not looking for a diagnosis (and I still have some more testing to get done), but any experiences or thoughts you all might have.
It has been at least three months now.
Thank you!
