After reading your symptoms i feel that you have lymphadenitis
ie: inflammation of lymph glands. Its a minor condition in which these glands get swollen when you have infection in the body. Fungal infection
may have caused it but usually it is overlapped with some other mild infection in the body such as common cold
or throat ache.
I would suggest you to take an anti fungal drug along with an antibiotic and a painkiller as well. The sweeling should subside within a couple of days leaving your body infection free.
