Hi Mrs Overall, thank you for your reply. He was sick during the night so it was quite a few hours after he had taken his evening tablets so prob would have absorbed all his tabs by the time he was sick. He's told them at clinic that his leg often hurts, always the left one but they never seem to want to do anything about it.
He saw the Doctor this morning who seemed a bit baffled but thinks the same as the hosp that it is connected to the water retention he had 2 weeks ago when they changed his meds and that it has damaged/bruised the soft tissue and all he can do is take paracetamol and rest it.
It seems a little better today, still very painful tho.
Thanx for your replies :o)
