New to asthma and, though desperately trying to inform myself, there is still so much I don't know. My son had an asthma attack today. It came on fairly suddenly and settled after using his reliever a couple of times. His chest remained sore for a good while afterwards and he said it was much sorer on the right than the left. Is this normal? I ask because I also noticed that his right arm and hand were shaking all the time. This hasn't happened to him before. Maybe he was just a bit shocked after it coming on suddenly but wondered if it's an asthma thing? Any advice/experience welcomed!
