Hi, I went for a 5km walk for the child cancer benefit. It was nice and very sunny. After the walk I came back and sat on the grass. I was wearing a capri pants that covered up to my shins.Next day I noticed that my legs are swollen, and itchy up to the shins. The next day my legs had swollen up to the knees. The legs feel very itchy, painful and red. Can you tell me if this is due to some allergic reaction. Some body was saying that it could be due to blood clots.
Thank you.
