You have not specified the amount of time that you have had this problem for. Although it is normal to get a throat tickle, it is unusual for it to remain for more than 48 hours. If it has been around longer, then you need to see of you can do something about it. If you have a small piece of fishbone or a scale irritating your throat, it may be the cause of your discomfort. Eat a large loaf of slightly moistened bread, to remove the offending particle.If this does not work on the first try, repeat the process a little later. If there are no positive results after your second try, you can safely conclude that there is no particle obstruction tickling your throat. It is also possible that you have a tiny boil towards the back of your throat that is irritating you. This is not uncommon, especially if you have just had a sore throat. While it certainly feels like a moving object and a tickle, it is totally stationary and does not move at all. Conversely, it is your throat which moves and gives the impression of movement of the boil. Add a teaspoon of honey and a pinch of turmeric to a glass of warm water and drink it before going to bed to get rid of the boil. You could also have a glass in the morning as this will help to speed things up a bit.
Since you only get this tickle at night, it is possible that what you are actually experiencing is a mild allergic reaction. If you have recently got a new blanket or pillow, it is possible that you may be having an allergic reaction to it. This is quite probably the reason if you sleep on your front. This is because your face is in contact with your pillow and so as you breathe in the allergen, you get a reaction. If you smoke regularly, however, or if you live with someone who does, it is possible that this is a more serious symptom and you should consult your doctor. In any case, if your problem does not clear up with a week or so, you will have to visit your doctor for a check-up. You may have to go in for several further tests, but it's important that you find out exactly what is wrong so that you can remedy it.
