I had my AZ vaccine 4 weeks ago. A few days ago I noticed a red rash on my leg, in a line on my inner thigh. It has now changed colour from bright red to a more faded purple like a bruise. It's not raised or been at all painful so I've not really thought anything about it, but tonight I read something about blood clots and started to wonder if this could be one? I'll post a photo if I can....
