What Causes Pus Filled Blisters Around The Groin?

Hello, Recently (as of yesterday), my groin and the surrounding region has been affected by several strange lumps with a reddish and crusty appearance. They secrete pus, are highly discomforting and are mildly painful. I am unsure as to how this may have occurred but it may have been caused from too much friction within that area. I have no food sensitivities or allergies and I have never had a medical history with this. I have, however, had a history with eczema (specifically on the backside of my right hand) and I believe that it may be possible that this is its ugly sister. What is your opinion? What should I do? Thank you for your help! :)
