Cronic pain for months.?

So sometime in April I was taking multivitamins. It gave me weird side effects so I stopped taking them. But then I ended up having this cronic pain that is sometimes directly on my right rib or near my kidneys. It is really bad in the morning then either gets better or completely goes away later on in the day. It gets better when I drink water. I'll be making an appointment soon but do you think the multivitamins damaged something? 26 female
