Hello and thank you for your question.
For a sore tongue that has been sore for three years but does not have any physical markings I would suggest that the tongue may not be the source of the pain. You may be experiencing what is called referred pain
. In other words you feel the pain in your tongue but it may be originating in another part of your body, like an ulcer in your stomach, or a tumor in your jaw (these are just examples not me stating you have these). Your tongue pain may be caused by glossitis
, inflammation in the tongue as well. Causes of this include vitamin B12 deficiency
, Sjogren's syndrome, and side effects of medications or chemotherapy
Since you are chronically taking prilosec
, this may be due to a vitamin B12 deficiency. According to one study I read when used over a long period of time, such as three years or more, prilosec can cause a vitamin B-12 deficiency. Signs of a B-12 deficiency include a sore tongue, unusual and unexplained weakness and numbness
in the hands and feet.
I hope this helps you in your discovery of your problem. I recommend taking a Multi-B vitamin and see if the issue subsides in a few weeks.
Best wishes and good health
