I'm 63 and been doing a lot of heavy yard work for the past two weeks. During this period I have experienced: 1 time became confused which lasted about 2 minutes, about 5 times had some numbness in my right shoulder/upper right chest area, 3 to 4 times have become lightheaded when standing up or bending over quickly, and the left side of my face had some minor swelling from my eye to my mouth. None of these happened on the same day. Right now all I have is some minor face swelling. Your recommendation?
