4 days ago my mouth started hurting slightly the next day I started to get a fever of 100 n started to get sores on my mouth tong  gums and cheeks, the next two days I  I had the same symptoms except with 103 degree temp then the fever has gone away however the sores n swelling have not gone away and they are very pain full, I thought it might be thrush.
Hi, It can be due to dermatitis or gingivostomatitis or gingivitis that causes your soreness over the mucosa of mouth. You can take antibiotics (cephalosporins group preferred)with analgesic, anti-inflammatory and vitamin B complex with folic acid, Chlorhexidine oral mouth wash would also help. Just see your family physician or ENT surgeon. You will be alright after this.
