African Tumbu Fly Infestation

It felt like something chomping away inside my left thigh and it hurt. My doctor couldn't imagine what the strange swelling was; it was shaped rather like a pyramid but without definable edges. To my horror, my doctor looked slightly amused when I suggested I had brought back an illegal immigrant from my West African holiday. 'There are two little puncture holes here,' she added, pointing to the tip of the swelling. Only later did I learn the purpose of those two tiny Vampire-like punctures - and it wasn't pleasant.
