Been doing it for years. That will help flow and make easier to get hot water through it.
If it's a Sealed Pressurised system (Combi OR conventional boiler) make sure system pressure is kept topped up to around 0.8-1.0Bar on the gauge using the fill loop that should be there attached to mains cold.

If you have'nt been using your heating for some months. Was the rad in question turned off at the thermostatic radiator valve... If it was.. they often get stuck in the closed position.
I would try supporting the back of the valve with the head of a hammer, and just hit the body of the valve with something ... the valves often stick closed after long periods of not being used.

I'd go for the TRV. At least one of ours gets stuck every year. If you unscrew the knurled collar below the control bit( that usually looks like an upside down plastic cup) and take the whole plastic bit off, you will see the little brass pin . Tap it VERY gently with something (like a pin hammer) and it should pop up. Screw the control back on...job done.
