I recently had a blister on my middle finger caused by what I thought was eczema?




Hi, I recently had a blister on my middle finger caused by what I thought was eczema, the blister has now become painful and seems to be infected, I used a sterile pin to pop the blister a few days ago. What would you suggest doing? I am going away traveling in 2 weeks and need the best sort of plan of action? Does it look infected? Should I visit a GP?.
It has began ever so slightly throbbing and is very painful to touch, I can also semi see a beating of red around the effected area. Thanks
