Hi Sir/madam...i Hav Had About 5 Ml Of Toilet Cleaner

Hi sir/madam...i hav had about 5 ml of toilet cleaner which contains acid and is corrosive before 3 months and was taken to hospital and kept in observation for 2 days and i was doing fine except that i was a bit dizzy so after that incident occasionally i am having mild stomach pain for sometime is there anything to worry about?
Thank u
