hello and welcome to HCM,
You seem to be having symptoms of an upper respiratory infection
and the bumps are papillae and follicles which swell when you have an infection.
Also since you have a nodal swelling it is imperative that you see a doctor right away so that a proper treatment can be started
Most of the time with adequate treatment all these above signs will subside
take care and get well soon
Dr Sriram Nathan
