Grunne

Hi forum, so a few days ago I brushed up again a bush that immediately gave me a feeling almost like maple syrup on the outside of my left forearm. Around 2 days later I woke up with a large painful red rash on the inside of my left elbow and a much smaller and almost no pain rash on the same spot on my right arm. They both stayed the same that day. The next day it had a some slight bruising on it. Next day, the rash starts getting a little flaky and some small cuts appear on the rash. Later that day, I was mixing up words like "phone" and "camera" or "Tv" and "radio" and didn't know it 'till reminded. This happened maybe 5 times just over the course of maybe a minute. Then I stopped mixing up words. Today, I was on the computer and I was feeling fine except the rash became a little less painful. Then I dizzy and felt like I was about to fall asleep but then I snapped out of it like 2 seconds later. I'm typing this on the same day and I'm just wondering if this is a tad bit odd? Extra Info: I'm 15 and I was on the computer working and watching videos for most of my day on these days due to a video project.
