Reasons and treatment for swollen skin

Our ten year old son recently had a huge area on his calf that was red and swollen. We'd been out in the garden so we assume he was bitten by something like an insect or spider. He said it was itching so I told him to put lavender on it but he couldn't find it so I suggested peppermint and it worked. The itching was relieved.

What else could swollen skin be?

It could have been because we haven't cleared all the tall pasture grass and weeds from the middle of our garden beds yet.

    I read some medical atical might be a serious thing ,signs of cancer too .I hate to talk about it but if there is any kind of swollen skin and scratchy on the face and parts of the body must go for checkup .especially men who smoke .

      Yes the swelling went down. After he put peppermint on it he did not mention it again until I asked him how it was doing.

        It was the size of his calf so I automatically assumed bug bite, but I didn't look for puncture wounds.

        I am not sure what a tick bite looks like.
