I have just recently started a work out routine, going for a run, sit-ups and push ups. Iv been doing it on and off for 2 weeks now, but for the last two days Iv had random stabbing pains around the liver , directly at the side under my ribcage !! Could this be an internal problem, or a reaction to the new exercise routine ? ?I m sure its easy to confuse the two, but I hate going to the doctors, in fact, I dont even have one, its been about 12 years since I last went !!
