Hi DS, 8 years, does not seem himself the last couple of weeks, he is complaining of sore head, dizzinness, sick tummy, his eyes are very sore and red at lot of the time as well. He is also complaing of sore knees at lot as well. he just really does not seem to be himself the last while. He does have extreme short sight and does wear glasses, he had this eyes tested a couple of days ago, they are not sure what is causing the eye pain or redness in the eyes but the doctor did comment on it, just told to clean with water for now and bring him back in 3 months, when they will probably increase his glasses again. It just seems he has a lot going on at the moment, should i be worried?
