There is nothing which can get dislodged below the ears.
The only problem in such conditions is swelling or edema inside the throat which i hope you do not have , and which is evident by the change in voice and difficulty in breathing.
If this is not there then there is not much to worry about .The lump could be a swollen lymph
node which could have been there previously also but has become evident now.
You can take a antiinflammtory medicine and still if the pain persists then you need to consult a doctor and take antibiotics.
In doubt do reply
