Turns out that injecting semen into your arm doesn't cure back pain after all

A man in Ireland repeatedly injected semen into his arm in the hopes that it would cure his back pain. He instead got a subcutaneous abcess and had to get professional help. [via Gizmodo]

Drs. Dunne, Murphy and Rutledge report:

A 33 year old male was seen complaining of severe, sudden onset lower back pain. He reported lifting a heavy steel object 3 days prior and his symptoms had progressed ever since. This gentleman had a history of chronic low back pain without neurology. Thorough physical exam of the upper and lower limbs revealed an erythematous papule with a central focus on the medial aspect of his right upper limb. His ASIA score for neurology was normal and non-contributory. The patient disclosed that he had intravenously injected his own semen as an innovative method to treat back pain. He had devised this "cure" independent of any medical advice. … The case also demonstrates the risks involved with medical experimentation prior to extensive clinical research in the form of phased trials inclusive of safety and efficacy assessments.
