Upper right stomach discomfort?

Recently with a significant weight gain, heavy alcohol consumption, and poor diet, i have noticed not necesarily a "pain" but a discomfort in the upper right stomach area, and slighty in the surrounding area. Also have the same, in the same area, but on the back, as if I pulled a muscle in my back. It only really hurts when pressure is applied to the certiain area. I have felt no naseua, and have not noticed any difference in urine or stool. Any ideas? And any advice to what I can do?
I have had my liver tested and that was ok, as well as my intenstines.
I am only 19 and havent been drinking for more than 2 years

Pain in the upper right area just below the ribs can be associated with gall bladder problems, especially if there has been a severe and rapid weight gain. Gall stones can cause great discomfort or can go unnoticed. Many people live their entire lives with gall stones and never know it. Others suffer terribly.
If you eat greasy or fatty foods and experience discomfort such as bloating, severe belching, difficulty digesting and more pain it the upper right area, it could be from the formation of gall stones. The stones can block the flow of bile which is used to digest fatty foods. Chalky and very light colored stools are another indication.

Gall stones are not stones at all. They have a rubbery texture and consist of bile salts and cholesterol. While many doctors remove the gall bladder, there is a natural remedy available on the Internet that worked for my husband. It is called the "gall bladder or liver flush". My husband was diagnosed with gall stones and scheduled for surgery. The symptoms he experienced left a week after trying the gall bladder flush on his own.
You should get checked by a doctor before attempting to treat yourself.

Sounds like it could be gall bladder. You should have it checked by a doctor. I had to have mine removed but I had to gallstones. He said that my gall bladder was very diseased though.

Better see your doctor again for colonoschophy. You might have ulcers or swollen appendix. Try to drink YAKULT everyday. This might help. Also, drink non-sugar coffee.

probably gallstones i was feeling the exact some way until one day it hurt so bad i cried and they forced me to go to the er you it could possibly be diseased too or you may have just pissed it off with all the drinking and the poor diet

Two possibilities for the cause not a diagnosis of what might all be involved
Heavy drinking does not only deal with the liver although it is good to consider it.it also deals with feeding sugar to the yeast overgrowth probable in the intestines which ends up poisoning the body with what it produces after eating sugar. (get rid of the sugar, use anti-yeast product that helps get the poison out of your system with probiotics to put back in what belongs there for this).
The other is that is simply muscles. For this read The Trigger Point Therapy Workbook by Davies.
