Uhmmm I was laying in bed beside my boyfriend and I felt a sharp pain in my arm like 10 seconds after I put it down I put my hand over it and I brushed something off its been 5 minutes its swelling and sweling is spredding was I bit by a spider o something ? Am I having an allergic reaction to something? And you can clearly see where something stabbed into me a small red swollen dot .

I am allergic to spider bites and still after two weeks have a red bump on my thigh. Yes, probably was a spider but who can really say what it was, a bug of some kind not very friendly with your metabolism.
