Hi I Was Stung Last Night About 630pm On The

Hi I was stung last night about 630pm on the top of my calve I believe from a bee. I didnt see it. . But very painful sting. Today my whole lower leg is very swollen down to my foot and the tissue say 6 inches across and around the sting is very hard and very hot to the touch. . As the day goes on the swelling is getting worse and is painful. I've been stung by bees before in my life and have never had a reaction like this. Should I go to Urgent Care? Thank you
