Three days earlier (unko ek chakkar aayi matlab 1 -2 min unko pain aaya aur unki body) this happen also 3 years ago, after we done angiography as well as all hearts treatment but nothing has been detected. Doctors says everything is fine and started BP tablet every day. After that we continuously monitoring and getting treatment but chakkar(vertigo) coming reason cannot be determined. After that yesterday they faced this chakkar. Please tell me actually reason behind why this is happening? What treatment should be done to get out of this (chakkar) Actually I am looking for best doctors for best treatment.
