My 12yr old daughter had been complaining constantly of sore bones, tiredness, nausea ect for a good few weeks, to the point she was unable to walk as it was to painful, after beginning the G.P they took bloods and we were informed her vitamin d levels were at 15😳 she was prescribed a loading dose of 10,000Iu for 8 weeks , we are almost finished them with no improvement at all, contacted the g.p to have bloods repeated and they said the labs wouldn't accept a second request within the year , and will prescribe a maintenance dose until she stops growing, how can they tell how much maintenance she needs without checking first? How would they know if her levels have came up? I'm hitting a brick wall as they dont seem to be bothered that my child can barely walk some days, has anyone any advice on what to do next? Or been through this?
