Bruising

[Sweet89]

Posting here for traffic.
I have scratched my leg tonight because it was itching, and it has turned into a bruise/rash
What is wrong with me? I had blood tests done at the beginning of the year, and it showed that I had ever so slightly low folate and was prescribed tablets for 3 months. When I was taking them, the bruising did get slightly better, but now its back to usual. Could I possibly need to take more, and is it possible to have such symptoms from slightly lower folate? Seems a bit much to me, I'm wondering if there's more going on? Has anyone experienced and/or experiencing similar issues?

I forgot to add a picture

I have had that regularly when I was having irritation issues (in fact, far deeper). There was nothing wrong.

I bruise very easily and get those pin prick marks with them too. My blood tests are normal. Some people are just more sensitive to bruising than others I think, but obviously check with a GP if you're concerned.
