is it ok to take methylcolamabin sublingual b12 5000 mg with shots

I have a very low vitamin b12, 88, was the number. I have symptoms of extreme fatigue, tingling and cold hands and feet, very weak arms and legs, tingling nose, nausea, frequent urination, diarrehea and stomach pain, and just an overall crummy feeling. I also have been having sinus and ear infections for the past year and it is hard to keep my sinuses clear. All my other labs were good except my WBC was 2.6. My dr. started me on vitamin b12 shots, 1 a day for a week and then 1 a week for a month and then once a month. I have had 8 shots total. I still do not feel very good at all. My question is, Is it safe to take sublingual methylcolamabin 5000 mg in every day in between shots? Or should I do something different? Any help you can give me would be appreciated.
