Swollen Muscle at Right Side

I am a 17 years old female student. I have a minor/mild rhintitis issue since young, i started consulting an ENT doctor at the age of 13/14. Recently i realised my voice is getting hoarse and there’s just plenty of phlegm that i couldnt cough up but it feels to be there, blocking my throat. I then consulted my ENT doctor again. He did a endoscopy test and he told me that its a minor GERD that causes my lymph nodes before my esophagus is swollen. After a month, i realised my right side of neck is swollen. So i got a ct scan and thyroid enzyme test under my doctor’s advice. Its not a thyroid issue nor any respiratory issue. He says its no big deal at all. Im still getting uncomfortable these days and i feel its still swollen and affecting me indirectly. I checked back my ct scan and realised the right side of neck is really swollen. Its swollen, but not an obvious lump. Need some help here, because on 17 only will i be able to meet my doctor. Thankyou for reading this and answering my question. I sincerely appreciated it.
