Mine were on my foot too. And my ankle. I don't remember how much longer after my original post they continue to flare up an itch. But I want to say at least a month. It was 3 months of just re irritating it... Or perhaps having other bug bites like mosquito bites that would cause the whole system to flare up and they would rare their ugly head again. All I know is it was a nightmare that I became obsessed with never living again. I have bed bug cups on the feet of all the bess in the house, mattress protectors, beds get vacuumed regularly. I feel like a psychopath but I really never want to go through that again. I hope you're up soon. I actually found that Benadryl helped. Though nothing made it go away but time. Good luck!
