See a good chiropractor, I would say you have misaligned vertebrae in your neck and the pain is radiating to your arm, etc. A few good adjustments, you will be as good as new.
It may be that the symptoms you have are an allergic reaction to the bite/sting and you will require an antihistamine.
Should the doctor suspect that the swollen glands are a bacterial infection, you would be prescribed with an antibiotic.
