Hi, I Am Having A Lot Of Pain Coming From

Hi, I am having a lot of pain coming from just under my right rib cage. When I press on that area it really hurts and I can tell that is where the pain is originating but it's also making my whole stomach area hurt like I'm cramping really bad. A few hours before it started I lifted something really heavy but there was no noticeable injury at the time and like I said it was a few hours later. This is day two of the pain and it worsens as the day goes on. Thank you.
