Yes! I'm sure I should know this but I'm unsure (want reassurance!) and can't seem to get my head round what google says 
I have flown before and taken ds liquid meds on the plane and had copy of consultant reports and repeat prescriptions.
He has changed medications since and has tablets crushed so I know I can take those.
However what about liquid pain meds? He can't swallow tablets and has CP and severe migraine attacks with loss of consciousness and myoclonus and if he gets pain or headache he will need the medication quickly as he deteriorates fast.
We have 1 hold bag but won't have access to that from 10ish until 3 ish (4local time) so putting it in here is not an option.
We have a cabin bag allowance but that is taken off us at plane door and so we wouldn't have it 12-3 (4 local time) but I would have the cabin bag going through security.
Am I allowed to carry a bottle of unprescribed pain relief though security?
The only other option I think I have is that WH Smith in departures may sell it (?) and I'll just buy some there as I can carry it once I'm through?
Sorry for most boring and first world problem thread of the day
