Thanks for writing to H.C.M. for your query.
I have gone through your clinical history about your throat problem. as you said the lump you saw and you feel in your throat is not your tonsil
but just in front of your right tonsil. This has changed your voice also.
Considering your complaints it appears as the lump you saw is arising from-
(a) Retromolar area.
(b) Lump from base of tongue.
(c) Lump from lateral pharyngeal wall.
To confirm the disease a thorough examination of throat is necessary along with FNAC from hard neck gland. In this way one can reach to correct diagnosis that can be manage accordingly.
