Cyst on left tonsil

Hi, I am worried and getting no where with doctors, about 3 weeks ago I noticed a white lump on left tonsil. Doc gave me antibiotics for 10 days...did nothing swab and bloods show no infection. Referral to ENT done but not heard anything yet. Been to see doc today as got no sleep last night due to pain in throat trying to swallow. Doc gave me treatment for oral thrush....not sure I agree. I am still in absolute agony and feeling awful. Getting no answers or relief from this pain. It's torture. Anyone any advice or tips to ease this pain. Worried it could be cancer but they taking so long to tell me ️
