11years back I suffered from rheumatic fever and was cured by penidure,LA12, but I didn t continue d injection for five years as prescribed.I used it for three years. Of late I have been frequently falling sick due to fever, throat infection ,boil,skin problem, heavy heart etc. My doctor asked me to re start penidure for 5years. Shall I follow his advise although I haven t suffered from rheumatic fever all these years? Please advise.thanks in advance.
