Have him tested for Lyme disease by a reputable lab such as IgeneX and find a Lyme Literate Medical Doctor, (LLMD.) Erythro is one of the symptoms of many Lyme disease patients. You do not have to remember a tick bite or see a rash in Lyme. Many ticks are the size of a poppy seed and over 50% of people do not recall a rash. Visit ILADS.org or Turnthecorner.org for more information. I have this and I have Lyme disease. Both are painful.
Hi,
All the symptoms of your son suggest of Erythromelalgia except redness. It could be a rare case indeed. Symptoms do vary sometimes in different individuals- it could be asymmetric or may remain mild for a few years for other patients. It could be the mild form for your son. The intensity of symptoms varies and that is why there could be a deviation from the normal significant symptoms. Please continue the treatment and advise your son not to soak his feet in extremely cold water because it may damage the tissues and cause complications. Hope this helps you. Take care and regards!
