Hi there, your abdominal pain and soreness could certainly be a result of over-exercise. I would like to know a little bit more information, however- are you having absolutely no soreness unless you are urinating? If you only have pain with urination, (and not at rest) associated with having to urinate more often than usual, or if you have any fevers or chills, I would be more concerned that you could have a urinary tract infection. If you have an infection, I would urge you to seek medical attention, as it often does not improve without an antibiotic, which you would have to have a doctor prescribe. If your abdomen has been sore all the time ever since you exercised several days ago, and gets somewhat worse when you urinate or defecate (from bearing down and clenching your abdominal muscles), it is likely just muscle strain and it will get better with time. You could try over the counter ibuprofen for relief. I hope this answer was helpful to you! Get well.
