Dear Sir I am suffering from a disease nevus of ota , that is one black spot near my right eye.I have started taken laser surgery from Bangalore.The doctor told that it will take 5-6 sessions every month in which i have already taken one session of laser treatment.He used Q switched ND Yag Laser-4mm using speed of 700 MJ,5H2 and charged around Rs 4000/session. The problem lies in my mind is that doctor told that it is not guaranteed that black spot will be removed permanently,it will only lightened.Secondly,he told that the black spot may arise after the all session will be completed anytime in future. Please suggest whether i should continue with other sessions or consult other doctors as i feel it expensive treatment because he is not giving guarantee for removal of black spot permanently and also telling a chance of recurrence.Rs 4000/Session seems to be very high in this case.please tell the cheapest treatment in Bangalore for such disease. Please suggest…..
