Sever stomach pain. Do to take it away?

I have been up all night in pain. There is an extremely sharp pain and pressure on the right side of my stomach right beneath my rib cage. The feeling is similar to a balled up feeling. When I try and massage the are my body reacts with an extreme amount of bloat and sharp pains through to my right side of my back. I have noticed that this usually occurs the same day that I take Famotidine 10mg Tablets for heartburn but I had taken the tablet earlier in the day yesterday around 10am and the pain started late at night around 10:30pm. It is making my back hurt very bad and I have no clue what to do to take this pain away I have already tried taking bloat pills and alieve. Nothing seems to help what can I possibly do to take it away?
