I appreciate all the concern expressed regarding my post run "issues." I have a few theories from my past backed up by some internet research.
I have struggled with colitis on and off throughout my life. My digestive system has had it's moments. A few years ago I discovered I was allergic to egg (particularly the yolk) which happens to be one of my favorite foods along with all those egg flavored things like ranch dressing, mayonaise, anything baked, etc. I seemed to do much better when I got egg out of my diet. Lately I have been cheating a bit.
Another possible issue - this one Terry has been discussing - gluten sensitivity. A few years ago my husband thought he had a gluten sensitivity - possibly celiac disease. Our family went gluten free and we have had some good results. Lately we have been eating gluten here and there. He was finally diagnosed to NOT be celiac. The interesting thing is that my sister has been diagnosed with it - and it tends to run in families, so....
Lately I have been under some stress - job changes and lots of travel. This combined with poor eating habits (really hard to eat healthy when traveling) and a digestive system that has been struggling a bit lately and, well it can cause issues. Add also to this an increase in consuming ibuprofen for inflamed feet and such and, well, you get the idea.
So, my theory is that my colon is stressed - the cramping I experience can cause the lightheadedness / near fainting spells (this is the only time I have the issue - is with the cramping). I am ordering a colon cleanse that I used with great success last fall - to hopefully clean things out - and then I should be back on track.
If this fails, then I will definitely get in to see the doctor!
In the meanwhile, even though Monday is normally a rest day - I really felt like running and my husband was ready to do a very easy 5 miles. So off we went for a run - I started out a little on a faster pace - I tried to keep it easy and eventually went from 5 min run 1 min walk to just 1 min run 1 min walk. I also tried not to let my husband pull my pace to quick. The last mile of the run felt great!
I feel a great week of running ahead! Thank you EVERYONE for your super support! :-)
