Hi. For the fourth time in my life I am suffering from a bout of red hot lumps on my legs and arms which face into bruises and swelling of my face hands and feet. I get this for about 3 months every 6 years then it disappears as quickly as it came. I was previously told that this was some sort of allergic reaction and given antihistamines but since being diagnosed with bd I have realised that this is probably erytherma nodosa. Does anyone else suffer with this and if so do they ever turn into ulcers as I have read that this happens in people with bd although mine thankfully haven't yet? Also what medications have people had for this as I am still taking the anti histamines with ibuprofen and paracetamol to relieve the symptoms and my gp will only give me steroids if my throat starts to swell.
