Dizziness 路暈

I walk to office from where my stay every morning and evening with each walk 2.2 miles for 40 minuets. It is the most economic, efficient, health way to remain my daily excises. the Road which I walk along is main traffic road, uneven, mostly the road all with up-down hill 30 to 40 degree angel sometimes. The side path way is around one meter width with more uneven and odd surfaces. After one month walk, my foot starts pain and I can't walk as same speed as usual. Sometimes, the pain starts at the morning walk. This week, almost whole weekdays, the pain from the lig. plantare longum appears at mornings and evenings. I am little worried. The worse thing today, when I walked back to home, during the journey, I was fainting for over 10 seconds which resulted me certain nearly hit by running cars from the main road. When I waked up from the dizziness, I was very scare. The dizziness is the first time in my life. I am getting older and starting aging myself. I must look after myself for my husband and beloved ones. Buddha, blesses me.
