10 Best Gastrointestinal Endoscopic Mucosal Resection doctors in Mulund

I am 17 years old male. Had fever 10 days back, then a swollen piece on my left side of neck at backside (i think lymph nodes), also having swollen gums from 2 days. last night i had a swollen thing on upper right side of stomach, pressed it gently, some squash sound came as if some liquid popped out, after a few seconds felt burning sensation on that area. It moved to the right side when i slept on right side, moved towards upper part of navel when slept towards left side. Had cold milk but nothing felt better. What could it be?
