Doctor: Hello, Welcome Thanks for consulting HCM,     I have gone through your query, as you have mentioned that you have undergone surgery of neck now you have blood blister and sore mouth, dont worry you first consult your doctor for this , if he said it is not due to neck surgery then should consult dentist and go for Oral Examination and investigations if necessary     As you are asking what it can be so it can be due to viral infection may be oral Herpes infection , or may be allergy induced or may be cancer sore or Angina bullosa haemorrhagicaSo consult dentist for Oral examination as early as possible,Hope this will help you. Wishing you good health.
