Hi Sahayog: As we said earlier abdominal pain can be caused by several things from very simple consitpation to life threatening conditions. Of course most often it is a very simple cause and you will be better ina few hrs. However, there is no definite way anybody can tell you without putting their hands on your belly and examining you and persistent severe pain warrant immediate doctor's attention no matter where the pain is. Well, health care in US is expensive but I am assuming that that you have some kind of insurance and that may cover bulk of your expenses. Even if you do not have insurance I would urge you to see doctor unless your pain is gone already. There may be certain hospitals where services amy be provided free of charge and in case of Emergency all hospitals are required to treat you irrespective of your insurance status. Your health and life are more important than anything and you will find ways to pay your bills even if you do not get free services. I wish you a good luck and speedy recovery and most likely its a simple problem that may settled by itself but seeing a doctor will give you peace of mind.
