I noticed several reddish large lumps on the back of my neck (with not known bug bites), then a few days later I noticed a dime size swelling on the left side of my neck that hurts a bit when I push on it. Do you think the second larger swelling (not red) came from the first limps? Also, what could have caused the reddish lumps? They look like huge swollen bug bites, with no infection.
