Try a different reed. What mouthpiece/barrel are you using? Which clarinet?
Many people say that the mothpiece, reed and barrel combination are far more important than the clarinet.

I'm playing a Buffet B12 clarinet, the original barrel, mouthpiece and ligature...I will go through some of my old reeds.

And also ensure you are generally well in your health. It sounds like an instrument problem but recovering from a heavy cold, flu-type illness etc can also cause such problems if you try to sustain a heavy programme of playing too soon.
If you're happy you, personally, are not the problem then I'd investigate further by returning to your old reeds and see what happens. If the problem goes away, you've got your answer - if it stays you'll need to check out other possibilities. What does your teacher think?
Hope you get this sorted - always a nuisance when you can't play as you want.
I'm pretty sure I'm quite healthy...I do have a slight cold, but I had these problems before, all through the summer....
Haven't spokenm to teacher yet. Think I might, I have my next lesson on Wednesday.
