im fourteen and i've been having 'growing pains' for a while now-probably since i was 7 or 8, they tend to happen at night- i've woken up several times with awful sensations too- and they usually occur a bit before a growth spurt... my mum found a homeopathic solution and we've found that that is wonderfully beneficial as well as putting cold cloths over the achy spots (this was passed on from my aunt, who also had them growing up) ..for me it's usually my legs or even sometimes my fingers!)
oh wow- i just realized this post is 6 years old.. well, hope his pains have stopped-if not, i hope this helps!
