Hi I'm 26 And I've Been Having Severely Bad Gas

Hi I'm 26 and I've been having severely bad gas for a couple of months now. And now my stomach hurts after I eat. I have been farting like 40 times a day and the smell coming from my anus is like 10 rotten eggs with sulfur and curled milk.. today, I've been burping and I am still tasting my dinner from last night. Even I can't handle my own farts anymore... and I can tolerate a bad smell with no problems but this is getting ridiculous. The smell sticks around for a long time too. Should I be worried?
