I've given him panadol and colic relief but nothing seems to be helping.
I'm unsure if you are feeding him solids, but have you changed anything in that area, it may be upsetting him.

I have a 10mth old, and she's teething, I have put her into a routine where she has something to eat, then a bath, a little play, then off to bed, I lay down with her with the lights off so she knows that's it's bed time, and sometimes I need to rock her to sleep on my chest, it seems to be working. I make sure she's in bed by 7.30pm and start the routine at 6pm, earlier if she seems tired. Some Bonjelia before the bottle seems to do the trick LOL

I feel your pain...
