The typical findings of vitamin B12 deficiency are numbness of both legs, progressive weakness, balance problem, cognitive decline, worsening anemia.
Tongue pain or weakness also may be seen with severe B12 deficiency.
Other symptoms from underlying causes resulting in B12 deficiency can be diarrhea, blood in stool, stomach pain, anorexia, weight loss.

Thanks for further information.
You will need to get upper endoscopy to check for celiac disease, H pylori infection, pernicious anemia as common causes of B12 deficiency.
Regarding, abnormal liver function test, you will need hepatitis panel, serum ferritin and transferrin, ceruloplasmin levels and liver ultrasound as part of further work up.
Thyroid abnormality should warrant further testing with thyroid antibody levels to check for hashimoto's or autoimmune disorder which can cause wide spread symptoms.
I see--Given that there is no explanation from the blood tests why your B12 level is so low even after injections, you will definitely need to push for endoscopy.
You should consult with a gastroenterologist if possible.
