I have csom, read for details. Up?

I have csom. Doctor gave me antiobiotic that i have to finish in 1 week. I finished it and went back to the doctor to get checked some mord. No discharge occured during the 1 week period. Then he told me to go home coz it will heal on its own, but to come back if the discharge persists within 2 weeks. 2 weeks laters, no discharge nor discomfort.. Slight hearing loss as usual but no discharge so i didnt come back. But now that im entering the 3rd week, my ear start draining, its not as bad as it used to be but.. A discharge nonetheless. Hmmm and a small bump on my earlobe. Also had a ringing in my ear but it went away asap. Should i go checked up? coz idk, it could be just nothing..coz a few days before i took a shower and was careless, i guess water got into the affected ear(im supposed to keep it dry)...then the discharge happened. Is it nothing or should i go to the doc.. I wnna make sure its something to worry abt bcs its a hassel to commute and I don't wanna do it for nothing.
