I understand that you are having some soreness and spots on your tongue. There may be many reasons for this, such as apthous ulcers, vitamin deficiencies, burns, mucoceles, papillitis etc..
It would help to know more on this pain and lesions as to there location and development over the days. This will rule out some of the causes and try and figure a probable diagnosis.
I hope this helped. Let me know if you may need any more help
