Epididymal cyst m29 weight 99kg

Since 16 l first noticed a pea sized lump in my scrotum however I am now 29 and have multiple ultra sounds and confirmations of it being an epididymal cyst it was the size of 2 maybe 3 grapes, larger than both testis however this morning it burst and I contacted my doctor and he said not to do anything about it, my concern is possible infection but was told antibiotics is not needed, should I push for antibiotics in case or is it generally harmless when they burst at such a large size, any response would be appreciated, thanks
