Hard small lump under arm doctor felt said prob a lymph node.took cbc lymph absolute3.3.have very small itchy rash and sore throat.should i be nervous?

Doctor can recheck: New throat pain can be from a strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor if the sore throat is bothersome, recurrent or doesn't go away quickly (mainly to check for strep throat). Strep throat can occur with a rash, but some viruses also cause rashes.
