Rash that looks like a sunburn

[aliceshea]

Hi everyone

I went out 2 nights ago and woke up in the morning with a rash that is about half the size of an A4 piece of paper. It looks like a sunburn, but not too red. It doesn't hurt to touch although the area feels tender on the inside. The area is slightly swollen and occasionally it aches in that area. Today, I have felt really weak all day and my left arm is sore, and i can taste metal in my mouth sometimes. I'm not too concerned with the pains today because maybe i slept badly. I've also had a headache behind my left eye for about 2 weeks now.

I don't live an unhealthy lifestyle, I go to the gym 5 times a week. I'm Australian so I like to binge drink occasionally but other then that I'm not that unhealthy. If any of my symptoms get worse I'll go to the doctor but it's more the rash/bruise thing i have.

Thanks for any help - I'm probably just being paranoid if anything

also 26 Female if that is helpful

All these symptoms are red flags, and I would urge you to see a doctor about what's happening- they will best be able to diagnosis you accurately, but with everything you described, I would get to the doctor for sure.
