Yannimac,
Thankyou for your reply. I certainly benefited from reading it and down the road my son will benefit from the knowledge if he has problems with symptom reoccurence with increase in activity. He is doing much better and we are now just hoping to get school back in order soon. He would like to run next fall but only time will tell. I hope you will get back to some exercise soon and I wish you all the best in your journey. Sharing the knowledge you have learned helps us all.
