Severe laryngitis for 5 days, voice recovered but still weak 1.5 weeks later.ent saw no problems with scope.how long for voice to strengthen? i teach

Hard to say: No pun intended, initially. A cold lasts 10 to 14 days, and this was most likely viral, so you're still really in the middle of it. The fact your voice recovered means you are on the mend. Take good care of yourself these next few days, hopefully by monday you feel better. Part of the reason you lost your voice is you use it a lot, as a teacher. Be sure to rest your voice this weekend.
