well last night me and my gf were fooling around in the park. I started feeling real itchy, and my face felt tight(maybe swollen?), so we started walking back to the mall. I started feeling worse, entire body red like a sunburn, and i had some breathing trouble for a few mins. I went home, went to bed and took it easy as i could. Woke up and my arm is swollen, and has pustules on it, hurts. Went to docter, he said i might have had a allergic reaction and a arm infection(cellulitis). He wasnt sure what gave it to me and said was to early to see. So he gave me anti-biotics. I started walking with my mom to my truck, and i collapsed in the parking lot(fainted i guess), so i had to go back in, where i had somewhat low blood pressure and then i left.. and im here where i am now... and very worried my arms are everything to me , i play guitar.
