Hi,I am Dr. Samiron Roy your ENT Splst.
The swelling beside your throat may be lymph node/ipsilateral thyroid
gland goitre/branchial cyst/carotid body
For these you need to get some investigations:
1.Hb, TC, DC, ESR, T3,T4,TSH.
3.USG of the lump.

Only after the reports are ready can treatment be planned.
