Im a girl and Im almost 16. A couple weeks ago I had a hot bath and after my bath I was rinsing off in the shower and the water was colder, but not super cold, just like luke warm. and I had my hands above my head getting shampoo out of my hair and my arms started aching so bad I had to put them down, then I got soo dizzy soo fast I just like collapsed and my ears were ringing and I couldnt see anything for like a minute. then I got out of the bath and my muscles ached soo bad i could barley lift up my towel. I went and layed on my bed and I felt light headed and dizzy and my ears were ringing and my whole body just hurt, I felt like I got hit by a car. then like 20 minutes later I was totally fine. Then last night It was really dark and I walked in my room and flipped on the light and I got super dizzy again and the exact same thing happened. also occasionally my muscles just ache super bad randomly durning the day.

what should I do?

But I didnt have any violent muscle contractions
