I have a small cut on my left tonsil. it hurts when i swallow after i wake up in the morning and i've had it for a few days now! should i get it seen?

Not bleeding?: Keep the area clean with good mouth hygiene and peridox. Eat a soft liquid diet. Hopefully it will he'll within 1 week. If not have it checked. If it is bleeding briskly, be seen. All the best.

Be sure of diagnosis: Get examined please. Canker sores are common aphthous ulcers of mouth that occur situationally, often in response to stressors, are bacterial or viral, & can be treated topically with many otc products that reduce local discomfort &potentially speed healing. However, oral/dental problems &a number of systemic diseases cause canker sore-like lesions--crohn's, behcet's, STD to mention a few.
