My 3 month old son had it twice too within his first 8 weeks of life. The doc told me that it is very common for it to come back again even after the 10 days of treatment with medication so when she gave me the prescription she gave me 3 refills for it. I treated my son twice and now he is fine. I wouldn't worry - just call and ask if you can get a refill for the meds (my son was on the same med) and it should go away. Good luck - I know it is hard and frustrating.
