My 13 year old son who is treated for Asthma woke up this morning with a bad headache, stomachache and was coughing. He came downstairs and was in a full blown panic and he was cold and clammy to the touch. He was complaining that he felt very weak, I had to help him sit down. Since he has drank some water and had toast. I had him lay back down and he still has all the symptoms except for the weakness. He has no difficulty in breathing and back in September he had his annual flu shot. Three of us in the house are battling the common cold type of symptoms, but his symptoms concern me because of the weakness and stomachache. Any ideas? Thank you.
