Is there any possiblity that you have been bitten by anything?
Hi there and thank you for the reply
Swelling and pain are indicative of a possible skin infection, and the splotching could mean the infection is spreading...so it would probably be best if you have your Dr take a quick look at it. If you don't have a regular Dr, you could see an urgent care facility and they can see you and treat you. In the meantime, try not to touch the area to keep from spreading the infection.
