In BMJ Case Reports, doctors are warning of the dangers associated with injecting natural oils to improve muscle definition following a serious complication experienced by an amateur bodybuilder.
The 25 year-old-man was referred to hospital because of pain and loss of function in his right arm over several months. An ultrasound scan showed a rupture in his triceps - a rare condition in young patients - and multiple cysts within the arm muscles.
He had taken up bodybuilding 4 years prior and attended the gym three times each week.
