Dear TS, since the doctor said that you're fine, you should think that you are fine too. Have you try to detox?
If i were you, i won't waste the time to think so much about it. There is nothing that really can be done rite? What if it turns out to be c***** or t*****? Even if it turns out that way, doctor may just ask you to wait and see. Not necessarily is a bad thing.

Just relax and go on with your life
