Erythema Nodosum????

My niece has been having these bumps for at least 1 1/2 months now and has been to the dermo 2 times so far. The second time was since they didn't go away and she was even getting new ones. They want to do a biopsy now and she doesn't want that but I have been researching and told my sis it might me absolutely necessary. Just wondering if anyone knows anything about these bumps (she has them on her arm too and in the beginning I know she had canker sores in her mouth as well). I am getting nervous about the other diseases that associate with that sometimes. What do you think should happen next (tests)? Is that the right kind of doctor to continue this?

Erythema Nodosum????
Erythema nodosum is a specific form of panniculitis characterized by tender, red or violet, palpable subcutaneous nodules on the shins and occasionally other locations. It often occurs with an underlying systemic disease, notably streptococcal infections, sarcoidosis, and TB.

Reply:Please tell her to go to a doctor that specializes in the blood. She needs to go A.S.A.P. My son had the same thing and they sent him to Barnes Jewish Hospital, in St. Louis Mo. They ran several test to see what the underlying condition was. They thought he had Rheumatoid Arthritis. Turned out that he just needed antibiotic, and then it cleared up. No underlying disease. Thank God. This is nothing to mess with. The dermatologist is not certified to treat this type of problem. He/she needs a specialist. Tell her to get referred to a disease doctor.
