bumps on my tongue

I just tonight found several bumps that are aligned up on the back of my tongue.  I have had a scratchy throat, and have been suffering from allergies lately, but have never noticed having these on my tongue in the past.  Also, I couldn't find anything like it online.  I'm wondering what it would or could be from, and if I should get it looked at?

Hi,

Tongue bumps may be caused by trauma, smoking, enlarged papillae, certain medical conditions such as  diabetes,  anemia or cancer.  If one or more of your taste buds becomes inflamed or irritated, it can swell and form a painful bump on your tongue.  If it persists, have this evaluated by your doctor for proper management and to rule out conditions mentioned above. I hope this helps. Take care and do keep us posted.
