Take a nice hot shower, breathe in that steam and relax. Lay off singing for a few days.

I'm not a doctor and this isn't medical advice. What I do when I have Laryngitis, is I go and buy two 100-count (meaning 100 horse pills in each) bottles of 1000mg Vitamin C.

I start taking them, 5 every quarter of an hour. Drink a lot of water.
At some point, you will reach a point of Diarrhea. You have just no reached what is called "Bowel Tolerance". A Vitamin C overdose causes this. keep taking them, and in a few hours, you will have your voice back.

BTW, you will feel amazing when this happens. I don't know what it is that causes it - but I know the Vitamin C overdose flushes all the toxins out of your body and you almost feel like you are walking on clouds. It is a very spiritual feeling... I remember when it happened the first time I did it, I thought,"This must be what it feels like to be a god!" LOL
It actually was probably the best I have felt as an adult.
Don't plan on going anywhere if you do choose to do this - because you are going to need regular access to the bathroom. And don't freak out, at some point CLEAR WATER will be moving through you, and I do mean out of your bowels - because you are going to completely empty out your system of all the food inside you and it will wipe out toxins from your system.

Steam bath for the vocal apparatus I can agree with, but not an intentional OD of any supplements. The high you might feel from something like that is a result of a toxic neurochemical imbalance, similar to overhydration i.e. water intoxication. I also have no idea what potential damage that could do to your body's natural filters, the liver and kidneys.

Personally, the furthest I'd go is to take a niacin (vitamin B3) supplement and drink a cup of water every 20 minutes until your skin feels hot and itchy and it looks like you're peeing tap water, then stop the niacin and continue drinking water at the same rate it leaves your system (roughly 16 oz. per full bladder, additional for bowel movements). Niacin is pretty widely used for system detox, especially by athletes after accumulating a buildup of metabolic byproducts from overexertion.

You may also want to follow each glass of water with a tablespoon of honey to coat and soothe strained tissue in your throat - just squirt it in your mouth, if you want, and slowly and gingerly swallow it as your saliva thins it down.

You could also try doing some low fry and soft falsetto exercises to loosen up your chords while breathing in that shower steam. I find these help relieve muscle tension around my trachea and pharynx and encourage freer movement of the vocal folds and surrounding tissues. Do NOT attempt full-voice practice until all your relaxed, low-volume exercises feel smooth and unstrained.

I hope these ideas help, let us all know what does/doesn't work for you!

Guys big thanks for advice! meantime my voice returned to normal, or have seemed to return. but couple days ago I discovered another problem. I weight only slightly over 60 kilograms and drink approximately 3,5- 4 liters of watter (together with herbal tea) everyday sometimes I guess 5 liters. Sometimes I drink like 2 liters in 3 hours before my workout and don´t pee really that much after workout when I go to bad. (maybe I breath out a lot of watter from lungs during workout) But couple days ago after such workout I woke up with headache and pain right inside my eyes. Then I got onto internet and read about a danger of idiopathic intracranial hypertension and I got scared like a hedgehogg. i don´t know how much watter is permissible in my case. I spent at least 45 minutes during workout, it takes really a lot of time to go all the way up. don´t you have any ideas about how much watter I breath out during that time.

OK, yesterday night and today I realized that my voice have not still returned to normal, also winter has come and the temperature went drastically down to freezing zero. I´m able to hit high notes, but it seems that I just can´t make it go up to soft palet fully. the tone seems to stay locked in throat and it´s not fully open like usually. I will try dose myself with vitamin C, will see what that does. Also I have to deal with much stress for the next 2 months as long as my exams are coming up soon.
