Cant swallow anything. Side of neck -?

Hello Dr, Myself lata khatri and i am 29 yrs old. From last 3 months i am unable to swallow anything and i am having swallowing neck so i went to the drs they gave me too much antibiotics but none of them are working. Then at last a doctor said me to go for ultrasound and i have gone through that. My reports say that:-A focal lesion is right side of neck - ? parapharyngeal abscess. Suggested clinical correlation and CECT Scan of NECK for further evaluation. . After going through this report i have gone for CT SCAN and the report was totally different from Ultrasound over their it was mention that :- Cervical Lymph nodes Multiple small enhancing lymph nodes are seen at bilateral level II regions, largest one in right side measures about 10*7mm and the left side measures about 12*8mm. I want to know that is anything serious and how will i know that which report is correct. Thanks & Regards Lata Khatri
