Hello, I've Had A Sore Stiff Neck For Weeks, Hurts

Hello, I've had a sore stiff neck for weeks, hurts if I put my chin to chest, itchy scalp bumps behind one ear, one side saliva gland will occasionally swell.
I saw chiropractor which appears to have made the discomfort worse. I saw him one week ago. No fever. Appetite good. No weight loss.
Thank you.
