Pain in rightside stomach. Right path.

I have a pain on right side in stomach and after taking antibiotic medicine course, it reliefs but after a month it starts again. There are no signs and symptoms appendices but it's severe pain cramps. After pressing a particular area I get relief. Have consulted with so many doctors and done MRI / Citi Scan / Blood tests but every doc give medicines for a month or two and pain starts again after a month. Not even getting a right opinion after consulting in so many big hospitals and doc. Also a doctor suggested to go for anti TB course which is completed but pain still remains, someone said it's infection in lymph nodes which is located in lower intestine and given medicines but it's still paining a lot. I am not able to find the right opinion from anywhere and being in place like Delhi, I am chasing from last two years. Anyone pls guide me the right path.
