Hello sir. Few months ago. I was tested positive for aso titre whose value was 400 although I don't have any symptoms at current but I have heard thar rheumatic fever can cause damage to heart and can cause neurological disorders. I am afraid may be I will get that. Although I never got rheumatic fever till now but yes I keep getting strep throat here and there each month which get better with azithromycin I am only afraid that I will catch any neurological problems. Please help me I am afraid too much.
