I got bit in the face 2 days ago by a mosquito I think?

Im allergic to mosquitoes as is, but Ive never had swelling like this before. I was bit on my cheek and my whole left side of my face is swollen. I have yellowish liquid coming out of it and its hard around the bite. Im putting ointment on it and putting a cold washcloth on it. I dont know if it was a mosquito or spider? Anything I can do to help with the swelling? It itches a lil bit, but its just so swollen and thats my concern
