Hi I started c25k 4 weeks ago and at end of week 3 I developed a migraine which I have never had before anyway because my face and arm went numb I had to go to Doc as they suspected a mini stroke! I ended up being checked out in A&E. This was really scary they said exercise was the migraine trigger now I am scared to carry on. I have had a week off. I am 49 and wondering if I'm too old for this type of exercise. Please can you give me some advise. Many thanks.
