Hii.. I Am Debasish, Age 26 Male. I Was Having

hii.. i am Debasish, Age 26 Male. i was having frequent thought infection in childhood even at the age of 15 to 20. but now a days it is reduced but sometimes i am having the same issue. last year i got high fever and the cause was not clear after several tests. My family doctor told me to do ASO titer Test. the count was around 700. Then i was advised to take Penidure LA12 every in 15days for 3 month, post 3 month in every 21 days. till now also i am taking the same. in between i have tested ASO again and the count was 600 around. So i want to know about the cause and the cure of this. should i have to take this Penidure LA12 for lifetime! Or is there any other way to treat this ? Please advise.
I am a working person and i have to travel place to place. i am facing so much difficulties to take this injection because, i need to convince the person about all my problem then only they are injecting. some are strictly refusing also. please hele
