Stiff Neck Hard To Swallow Are These Symptoms Of Tonsillitis?

Are these symptoms of tonsillitis? - stiff neck hard to swallow

I had a headache since Sunday, and it gets even worse when I get out of bed. My tonsils are swollen and it is really difficult and painful swallowing. Yesterday I had a fever and headache and stiff neck today. Thank you for your help. Ohh, and I get very dizzy.
