Thanks for posting,
Sounds to me like a throat infection
probably due to strep (given the symptomatic presentation). It might be due to a viral infection and requires only symptomatic treatment.
Well since you are blunt about not seeing a doctor and not having an insurance, it will be kind of difficult to tell you exactly what to do at home. You will need to do warm salt gargles or betadine
gargles, take OTC mucolytics, NSAID
and antibiotics to treat the symptom and the infection. Consulting a doctor would have been the right step to take.
Hope this helps
