Danny,
I will definitely be praying for you, but strangely enough, that sudden, painful type of swelling and inflammation is usually not what is the most dangerous as long as it doesn't have immediate, catastrophic effects. The things you would dread having the most, like cancer, grow much more slowly and are painless until much later in the progression of the disease. I know from personal experience what stage 4 neck cancer feels like, and it really didn't hurt, although the treatment sure did. Problems like you are having are VERY SCARY, and it would be nice to find out immediately what is causing that lump so you could put your mind more at ease instead of thinking of all the really bad things it might be. I could easily be wrong, but I suspect your problem will be something that is not as severe as you might imagine and will be very treatable.
I wish I were going to be able to see you at Solana instead of getting my knee cut on. At least being laid up for awhile will give me a chance to put in a lot of prayer time, and you will definitely be in my prayers. God bless you Danny.
Allan
