I had cryotherapy treatment five days ago. I've had a very, very heavy, watery discharge since then. (My pad is entirely wet after just a couple hours...the nights are really bad--I wake up feeling like I'm wearing a wet diaper...Ugh!) Over the past two days, the discharge has become more yellow-ish and has a strong smell. Is this really a sign of infection? I otherwise feel totally normal (although uncomfortable). No pain, no fever. Is some smell normal? When should I be concerned?
