Advised to go to ER as soon as possible...
I have gone through your medical history and feel sorry for the situation you are in.
As you are having severe pain
until the point that you cannot cough
or sneeze, to my opinion, you should go to ER as soon as possible to further evaluate what is really going on inside your abdomen.
You are saying to be suffering of pancreatitis
and hepatitis; the fall you had last night would have caused more damages to your pancreas/liver
until the point you are having a severe pain.
Next, attacks of pancreatitis are usually treated in the hospital; so, I highly suggest to get to ER for further treatment.
It is not true that there is no treatment option. If the attack is confirmed, antibiotics, fluid replacement and pain killers are used to ease the symptoms. A GI specialist should be consulted to give the most appropriate treatment to you.
Furthermore, if you are having hepatitis, the GI specialist should determine the type of hepatitis (viral, bacterial or just inflammation). Depending on the diagnosis, appropriate and specific treatment will be prescribed.
I understand you sad situation, but you deserve to live your life without having pain. In nowadays, there exist many treatment options, but you need to consult with the specialist to decide the best for you.
I would suggest to take otc pain-killers, but, I doubt they would work for you. At such high score pain, I would prescribe stronger pain-killers iv. Furthermore, they might cause bleeding, which might aggravate your situation. I need to rule out that you do not have any bleeding problems (internal/abdominal bleeding) while you were falling. That's why I strongly suggest to get to ER as soon as possible.
Hope it was of help!
