I had an ulcer on my right index finger starting 5 weeks ago it has now caused an infection underneath the nail which is extremely painful. I have had 2 courses of antibiotics, the last finishing 4 days ago, this has had no effect and the pain continues along with a pus discharge. My GP has taken swabs, still waiting for results. Has anyone any ideas of what I can do to clear this up? I need to take regular pain relief. I had Iloprost last November and am due to see Rheumotologist at end of month.
