What Is The Function Of Vicodin Over Tylenol?

why does vicodin work better than Tylenol with codeine when my legs lock up or front thighs start to hurt when I play soccer and when I kick? I get these mini shocks down my legs and spine and sometimes my whole body from head to toe. I notice it I get these pains when I work out, like doing pushups, treadmill only sometimes, and soccer. I also noticed when I get upset stomach and diarrhea, my muscles or leg tissues began to go into shock. pain is so bad made me fall to couch and felt like my whole body was a mop being wrung out. twisted is how felt two weeks ago but have not really had it that bad since then. yet I feel It in my thighs when I kick a ball. I did notice that three days prior to that attack I had eaten a lot of steak at hometown buffet and nothing much else just meat. also, I have been eating montectio salsa for a month now I bought it there every day I eat salsa so I stay away from butter. Could the tomatoes be the culpit? I eat a lot o f salsa every day because if I get hungry I just eat that to calm hunger at night. what should I do?
