What Causes Swelling On Temples Along With Red Spots On Arms And Hand?

I recently had some swelling on both of my temples, mostly on the left side of my head. It started after I started exercising more frequently, after a couple months. I also experienced swelling under my jaw on both sides, a slight shift of my left eye. I m losing some hair, but I m not sure if it s more than normal (because I have always lost a bunch of hair when I wash it, but have a lot of it). However, I m startimg to notice my hair thinning a little, only on the top now. The swelling has gone down after I stopped exercising for a while, but sometimes I have a slight pain behind my eyes and my eyes appear starange and sunken. My skin is strangely dry and I m getting some red spots on my arms and hand, and had a couple on my foehead and left eyelid. What could be happening to me?
