My daughter has been diagnosed with Erythema Nodosum, she has the classic symptoms of lumps in her legs from the knee down. They swell, feel of fever and are painful and leave buising on her legs. She is in Grad School and it is very hard on her to walk, because she is also working and on her feet all day. She does not have insurance since she is over to age to keep her on our insurance. She is alway looking for any help to ease her pain and I am really worried about her and we have already had her nineteen year old brother go thru Hodgkin Lymphoma and it is a real concern if maybe hers may be some type of cancer, even though she has been tested for everything that is listed it could possibly be related to except the cancer. She has been told she needs to take B12 shots which can only be prescripted by a Doctors, is there any other sugguestions she could get the B12 thru, like a pill or something?
