Problems with sores

[janquito1959]

I hope I can get some information. I've had problems with my skin all of my life in one form or another; hives/welts as a child, chilblains, eczema, dermatitis, sores from who knows what and now I have a diagnosis of prurigo nodularis. I noticed (and mentioned to my gp) that when I'd gotten some injections for migraines (Toradol) and cortisone injections in the lower back, I'd get sores which seemed, to me, to go along some sort of line (not straight) like a nerve. My gp said to her it sounds like it could be an immune thing. Afterwards, I started thinking back and it dawned on me that since having had at least three EMG's over several years, my legs and arms are filled with sores. I never had sores in these places before but I also have sores all over my back, too. Could this  have been caused by the EMG's and could it be some sort of immune thing?

Thank you for your response. I did get in to see my dermatologist. I was 'fortunate' to have one of the nodules so he could see it. He took a biopsy. He suspects Behcet's Syndrome/disease. The results came back: " Skin with dermal edema, perivascular mixed inflammation with
lymphocytes and neutrophils and interstitial neutrophils. The histologic
features are not specific ". And then this was included at the bottom: "Diagnosis Comment
This case was seen in consultation with Drs.####### and ########of Mayo Clinic-Rochester.  Please see Dr.##### report for
additional diagnostic information and a detailed discussion of the
differential diagnosis."
There wasn't anything included so I responded to it saying it made no sense to me and where is the diagnosis comment. The nurse said she sent the doctor (my derm) a note and hopefully he would get back to me the following Monday which is tomorrow.
Any further thoughts from you?

Thank you,

Hello,
The cause of prurigo nodularis is unknown, although other conditions may induce PN. PN has been linked to Becker's nevus, linear IgA disease, an autoimmune condition, liver disease and T cells. It is less likely to be triggered by EMG.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
