Hi. I Have Been Dealing With Erythema Nodosum For About

Hi. I have been dealing with erythema nodosum for about 20 years and I am now at the point where my flares are lasting longer and becoming worse. It hurts to stand, walk, sleep or even sit. I am a young 47 year old female but I work in a medical office. I was talking to someone about disablity but was not sure if it were possible. Thoughts?? Thanks
