I have been having severe pains throughout the day today. It's between chest and stomach. Lasts about 30 min each time. Is it possible that it is gas? It feels like when you have to make a bowel movement and you get the cramps in your back but the feeling is in chest/stomach

You need to be checked out by a doctor. You could be having gallbladder problems. It is a serious condition and requires medical attention right away.
