<s>[INST] I have had a lump on the bottom right side of my tongue for awhile at first it had a squishy feeling but it got larger and now it is more firm & a lighter color. I had looked it up and found something about a salavary stone, but it said that would go away on its own within 5 days & it has not gone away or gotten smaller. Any thoughts on what it could be? [/INST] Hi... Welcome to Chat Doctor. As per your complaint you have problem of lump under tongue, and it increases in size also. Clinical examination of lump give more information. Size, shape, color of mucosa, consistency of lesion give more exact idea about lesion. Consult an oral surgery for further diagnosis. Biopsy and histopathology can be done if needed for further diagnosis. Occlusion x-ray can use to evaluate salivary gland stone. I hope my guidance helpful to you. Take care. Thank you. </s>
