What Causes Light Headedness And Temple Pain After Lifting Heavy Weight?

I ve started doing a weight-lifting routine with a trainer. It s been going well, but as the weight has gotten heavier, I ve noticed a slight throbbing in my right temple after working out. I m also sometimes a little bit lightheaded. I m a 59-year old woman who s always been in fairly decent shape, and I ve worked up to the current weight levels I m lifting slowly. I don t have muscle pain. Thank you.
