3 day headache, full body muscle pain and it hurts to pee

Hi everyone. I (F21) have been dealing with immense pain for the past 3 days. It start two nights ago, where I started feeling really cold but my skin was flushing. I did feel anxious a few hours before that I believe might have been induced by a drink with green tea and apple juice (I'm sensitive to caffeine).

My muscles ached a lot. And my head hurts. I also noticed some raised skin (skin writing) so I took an anti histamine.

I went to pee (I started drinking water with electrolytes because I thought it might just be dehydration. I often forget to drink water and lie in bed most of my day). My legs started shaking and it hurt to pee- not in a burning UTI way but like the pelvic floor muscles hurt.

The next morning I also woke up with a throbbing head and muscle aches. I took ibuprofen. I felt weak throughout the day but the painkillers helped.

Later that night my entire body hurts. Headache, back of the knees, my lower middle back, my jaw (I have TMD) my ankles, my elbows—all my joints. And it still hurt to pee. On top of this, I felt like I wasn't digesting dinner.

This morning I woke up to a throbbing head and weakness in my muscles. Now I feel a sensation in my throat and a fullness in my stomach, and I can taste what I ate last night.

I've been absolutely miserable, but because I don't have an actual fever or diarrhea my mom said going to something like CVS's minute clinic would be a waste of time. I've always had digestive issues and I have food sensitivies, so I've had flare ups with musculoskeletal pain before, but never to this extent. At least not to my knowledge. What do I do?
