I have swelling under the chin from last 10-15 days, I had swollen tonsils which now 40% reduced to the normal size, also had a sore throat that time. But now that has gone, but this swelling is as it is, also I feel like something is stuck under the throat, this feeling is not consistent throughout the day. Attaching photos of swelling for reference, kindly guide me, since Google results are scaring me to death.
