Please help! (Pic included)

I'm not sure if I'm having an allergic reaction or what it is! My lips are super dry, burning, itching, the corners are spilt, bumps on my actual lip, numb, tingling, and also swollen. I haven't eaten anything unusual except for an off brand kind of cheese. Please help me. I'm also breaking out in my calf. I have taken Benadryl pills. It helped the swelling go down, but they still itch and burn.
