The exact cause of your symptoms can be decided only after a clinical examination of your tongue. Tiny bump on the side of tongue can be due to constant irritation of the fungiform papillae. Small bumps can be caused by oral herpes simplex virus complex, allergic reactions, early stage syphilis, canker sores, bacterial infections or tuberculosis. Immune disorders can also cause tongue bumps. Mouth cancer can cause a lump or area of thickened skin on the side of your tongue. A clinical examination is must. Treatment will depend on the underlying cause. Seek medical opinion. Keep me posted.
Best luck and regards!
I will go to the GP and have this checked out as soon as possible but from looking at the pictures I have attached, what are the odd's that it could be cancer? I know that you cannot give a full diagnosis without an actual examination. By the way, I also can swallow fine, eat fine, there is no tongue pain and I don't have a sore throat and I have no red patches on my tongue.
