Husband is pissed that I have a uti

So it’s almost 11 o clock at night and I’ve been peeing a lot and feel like I can’t get it all out. And it burns when I pee. I’m pretty sure I have a uti so I asked my husband to get me uti medicine since I’m in pain and peeing every few minutes. He got irritated and left to get me some. He hasn’t gotten back yet, but I kind of got offended that he got irritated. Like I’m sorry I’m in so much pain, not my fault! I would do the same for him…should I be mad?
