<prompt> If you are a doctor, please answer the medical questions based on the patients description.my sons asthma is flaring up after running in PE. His inhaler is not doing anything for him and the pick test ? they did at school was at 340 and for his age and weightsize he should be at 450-460-per the school nurse. i brought home to use his nebulizer. his is numb along with tingling in his hand. what should i do?  <response>: Hello, Peak flow at 340 Lmin is not too bad when one is having an acute asthma attack although this would depend on the persons age and height as you mention 460 Lmin. Less than 50 of best peak flow is an indication for hospitalization. You need to ensure he is on: enough anti-allergy medications, a nasal spray, Singular 10 mg if adult, combination inhalers like Sere tide or Airtec-SFSingulair will help for exercise induced asthma exacerbations. A detailed allergen profile test is required to see if he will benefit from immunotherapy. Best Wishes.
