Could Advil be causing my symptoms?

I suffer from shoulder pain and headaches for which I frequently take Advil liquid gels. I would estimate that on average I take between 4–6 gel capsules a week. Very recently I have noticed slight burning during urination shortly after taking the Advil. I am prone to UTI’s and kidney infections however this sensation has yet to turn into anything more. I end up drinking more water and cranberry juice and it subsides within a few hours. It took me a little while to realize it always happened after taking the Advil. I have no infections, no UTI, no std’s. I can’t figure out why now, after years of taking the same type of medication, it’s causing me such a weird symptom. It’s my favorite pain reliever and would be disappointed if I had to change it. Does this sound related or is this in my head? Could it be that I’m taking too much of this medicine too frequently?
