Whilst being at the beach I was bit or stung twice on my foot. They blistered and was oozing for few days and went very hot and red. I was putting antihystermine cream on and also took tablets. After a week they have really gone down and now just look like 2 round scabs. Last 2 days though just lower than where they are toward the inside of my foot has been incredibly itchy like I can’t even describe. I’m concerned it’s something from the bites?
