I went walking on Sunday (3/4 length trousers and walking boots). Yesterday, I noticed a bite mark and a red circle / swelling around the area on my leg. Last night I had a bath and the bite turned into a big blister, which is weeping. My leg is sore around it (the red area). I’ve been bathing it with salt water and had a dressing on it. I can wear a dress tomo as I’m WFH (can’t do that in the office) but would you say this needs urgent medical attention, or do I keep going with the salt water and air it out tomo?
