Hi, my boyfriend has contracted endocarditis and ended up having to have open heart surgery to replace his valve 6 weeks ago. He has made a remarkable recovery, and has now finished his course of anti-biotics, and has been getting good feedback from his clinic visits/scans every 3 weeks. Since a few days ago though his elbow has become swollen, and has what feels like fluid around it - he cant remember if he has accidentally hit it off something. He said that he will go to the GP at the beginning of next week - I just wanted to check that it isnt something which should be checked out more urgently given his other recent medical conditions?
