my dd is going to be 13 next month.
she was a healthy girl but in the last couple of months we are experiencing some differences in her health. she is very tall for her age.
she likes to relax at half term, but I take her out at least once every 2 days.
yesterday after about 40 mins brisk walk she felt palpitations and she turned pale.
she feels them from time to time but yesterday got me worried.
what should we do? is this normal, will it go away in time?
thank you very much in advance.
