Hi my eldest DS, 14, has always been quite sensitive to aches and pains, but now always seems to have a body ache, or headache, and be lethargic. He likes sports but struggles with muscle pain and sore legs. He has a reasonable teenage diet, Omega 3 and 6 and vitamin supplements. Have recently started iron (Floradix) too, which seems to have given him a bit more colour, but not much else different. He always seems lacking in vitality / energy and his posture is poor, shoulders hunched. I have suggested we see the GP but he refuses and I don't want to force him to go to (we went once before when he was younger when I was concerned about his tiredness etc. and thought he might be diabetic like his Dad (he wasn't), he found it really uncomfortable and embarassing).. any similar experience or advice?
