A few days ago I shouted or screamed the loudest I ve ever done before & when eating later that day I had a dull pain under my jawline on the left side of my neck/throat. For the next 2 days bringing me to today I had the dull pain but only when ever I ate other than that it was non existent. Then after getting home from shopping earlier today I generally brushed my hand down my neck and felt this massive lump about the size of a gold ball. When I looked in the mirror it was clearly visible. So I shouted to my dad outside who was leaving for work, he booked an appointment at the doctors for 5pm by that time the lump had shrunk to the point where it wasn t so visible but you could definitely feel it. Anyway the doctor said I most likely cracked/tore the gland when screaming this then caused bacteria to enter when eating causing an infection. So he prescribed me a regular dosage of the antibiotics amoxicillin of 1 dose of 250mg 3 times a day, and tomorrow I have to go to the hospital to have a blood sample taken. Personally it feels like the lump ness has moved ever so slightly to the middle of my chin. Is this a serious problem to be worried about even after getting the medical advice. I am currently aged 15 and male & never had anything like this happen, and I am not too worried per say of what s happening but a little concerned on what could happen, could someone shed me some light on what is going g o?
