Hello Welcome in H.C.M. for consultation. I have gone through your query regarding nose bleeding and nasal cauterization three times in past and remain about 8 months free of bleeding nose but suddenly today you notice a blood spot and you land in mist of worry. Here first of all I would like to say that in the nose over nasal septum there is a area called as LITTLE S AREA which is supposed as highly vulnerable area for nasal bleeding because of rich vascularity. There are various factors responsible for nose bleeding like- (1) Hypertension. (2) Thrombocytopenia - Means decrease in platelets count. (3) Bleeding disorder. (4) Infections of nasal cavity. (5) Bleeding polyps (6) Growth in nasal cavity. (7) Deficiency of vitamins like vit - C and b12. Cauterization is a procedure to cease the leaking of blood from vessel but the primary disease should be treated properly (eg if anybody is hypertensive in that case cause of bleeding will be hypertension thus along with cauterization hypertension should also be treated otherwise bleeding will re occur). Keeping these possibility you should consult an ENT doctor to find out the cause of bleeding and that should be properly treated to avoid recurrence of bleeding. With Regards.
