What would urgent care do to help? ?

For about a little more than a week I’ve been having a constant headache. It’s mostly just on my right side, but sometimes it’s on both sides and near my temples. It’s been mostly in one spot on the right side, and sometimes it’s stabbing pains. I’ve also had stabbing pains on the top of my head and in the back. Right now I’m just having pain behind my eyes and near my temples. My right eye also has been burning. The only explanation I can think of is I just had fillings done and my bite isn’t completely right. If I went to urgent care, what would they do for me? Do you think I’d need an MRI? I also never ever have headaches, and this has been constant for more than a week. It’s also gets worse at night and is effecting my sleep
