On Friday I had a small red bump almost pimple like, but without a head. I didn't touch it or anything, I left it alone. By Friday night it was the size of a dime and slightly firm. This morning on Saturday it was a little bigger than a quarter now about 8cm in diameter with one straight line and one squiggly line coming from it. It's hot, painful and very firm and swollen. Went into the Er since doctors offices were closed. The doctor said it was a bee sting. I live in Wisconsin, it's currently 22 degrees F. with almost a foot of snow, I haven't seen a bee since September. Anyone have anything similar or know what it could be?
