Swollen lymphnodes in my neck and groin insatiable itching in places that I never thought could itch...sweats?

Im not sure whats going on with me, but Im a mess. Im gagging and throwing up all the time...my tonsils are swollen, my lymphnodes are swollen but nothing hurts. and over the past few weeks Ive got ingrown hair looking bumps on my groin. The throat specialist did a kat scan with no iodine because Im allergic and told me to go in the next day for an urgent appointment.....I went in and he felt my throat and gave me anti biotics and said that if the swelling doesnt go away in two weeks to go back, but Im freaking out. I havent looked anywhere else because I am not trying to freak myself...but Im getting sick of this itchy scratchy pukey stuff and I really just wanna feel better. any suggestions? someone? anyone?
