I suffer from granuloma annulare, erythema annulare centrifugum, erythema nodosum, and low IgM. Are these related or might they have a common cause?

Unlikely: These 3 conditions have 3 different auto-sensitivity targets, in the skin. Biopsy appearance is different under the microscope, and treatments are different. The first 2 conditions usually respond poorly to any cream, but are not serious. E. Nodosum can be a sign of a more serious underlying disease, and stronger meds are needed. Please see a Dermatologist for treatment. ...Read more

61 yrs old - diagnosed with Crohn's disease at 13. Ostomy 13 years ago. Erythema nodosum extreme on left leg.. . Very painful. Several years now.

Prednisone: This is a tough problem. The only thing that is going to really help with erythema nodosum is prednisone. I suspect you have been on Prednisone on and off for years and were hoping the ostomy would decrease the need for it. See a dermatologist who can collaborate with your GI doc. You are still having inflammation and I assume you are on other systemic medications. ...Read more

I have most of the symptoms of sarcoidosis such as fatigue, erythema nodosum, shortness of breath, but the test I took for sarcoidosis came back negative. Why the erythema and other symptoms?

Yes: If you have lymph nodes visible on chest x-ray or palpable, they maybe worth sampling and an angiotensin-converting enzyme assay ordered as well. This is a reasonable part of the workup for longstanding erythema nodosum. There are several other possibilities and I am glad you are taking a proactive approach to your health. ...Read more

I was recently diagnosed with Erythema Nodosum. My lab results showed my WBC is 11.1, SED rate is 41, and CRP is 14.4. Should I be concerned?!

No: Treat the person, not the lab values. These are trivial, and hopefully you already know that reference ranges are set so that several percent of healthies fall outside on either end. Of course something's inflamed when you have E-N, but you'll probably never find out what and most often it resolves. Let the workup continue, keep up with healthy lifestyle stuff, and plan to live a long & happy life ...Read more

I have the bruises on my legs that resemble erythema nodosum and I tested negative for sarcoidosis. Should I still have a biopsy to rule out erythema and possibly answer the question of what exactly is wrong with me? I've been tested for lupus and tb. Bo

Easy does it: As often as not, erythema nodosum appears for no reason whatever and goes away after a while. If you feel well otherwise, and are hepatitis c negative, and it was not precipitated by medication, and your physician is okay with just watching it for a few weeks, that's probably fine. ...Read more

Erythema nodosum what are the causes of this painful lumps in my legs? Since 2008 taking antibiotics twice! And they always come back, why?

Many possibilities: The most common cause is a smoldering infection in teeth, tonsils, bladder, intestine, or elsewhere. Since yours goes away with antibiotic treatment, that's probably what's happening. It is recurring because the infection is recurring - so your doctor needs to run tests to find the exact location of the infection and treat it more specifically. Certain drugs can cause it too, as can other things. ...Read more

Will erythema nodosum affect my baby and pregnancy. I am 12 weeks. Help.

Should be OK: Erythema nodosum is not going to have a direct effect on the baby but may certainly be uncomfortable for you. Medications that might normally be used tend to be either hazardous or at best untested for pregnancy, so your treatment options are pretty limited. It will generally resolve in a few weeks. ...Read more

Elevate legs.: It's best not to take medications of any kind during pregnancy unless absolutely necessary. Anti-inflammatory drugs, in particular, are not recommended during pregnancy. Elevate your legs as often as possible, and try to wait until after the baby is born to take medications - unless your obstetrician prescribes a specific one for you. ...Read more
