  • Glia on Oct, 4, 2014:

    HCP would most likely be the porphyria. As the immune system is continuously being assaulted by viruses and toxins, more severe symptoms, heightened allergies and other porphyria co-dependent conditions will be expressed more severely. This is especially true if the assault is in curable. I expressed porphyria starting with menstruation in 1968 and was misdiagnosed. More extreme symptoms developed when exposed to an untrialed anthrax vaccine and supsequent Enterovirus in 1991, and was also misdiagnosed. Debilitating symptoms began in 2004 with HSV2 infection in 2004. With the addition of Valtrex, the combined undiagnosed acute porphyria, genital herpes and porphyria drug intolerance complications resulted in a correct diagnosis in 2008. The severity of the allergy and immune complications of the interaction of acute porphyria and incurable neurological disease has resulted in extreme allergic and neurological reaction to almost everything that could cause an immune response from MSG which causes a severe rash as you describe, plus anaphylactic reaction to severe colitis(Crohns), skin intolerant to sun exposure(severe burn, rash and nodules),cysts (epidermial & ganglia), fibromyalgia(originally diagnosed as RSD cause unknown), muscle weakness(extreme after severe porphyria attacks) and recurring kidney infections and migraines. It is important to eliminate all exposures to toxins (especially ingested & skin contact) and virus infections. As a human in this ultra-connected, chemically polluted world, this is pretty much impossible! But trying is the best we can do!


    Maureen Zelmer on May, 31, 2010:

    I was prescribed this drug for my severe rash by a doctor that didn't know my history. I was exposed to Agent Orange in the late 60's while living in Base Gagetown, NB, Canada. I was in a lot of discomfort with the rash but when I took the Hydroxyzine HCI(June 22 09), within a couple of days (June 26)the rash became unbearable. I actually had some thoughts of driving into a power pole. The rash spread up to my chin, covered both arms (into the armpits). The medication seemed to cause the rash to spread rapidly and be worse in every way. I then looked at the side effect sheet that the pharmacist had given me and it said that it could make PORPHYRIA worse. I am undergoing tests for Porphyria Cutanea Tarda (caused by Agent Orange exposure)but what a gong show!!!


  • From this study (1 week ago):

  • Not sure if the methadone is giving me the heart palpitations or the anxiety about being on the methadone is giving me anxiety. I have a heart monitor right now and I had an attack yesterday and I felt like I was going to die. The dr. and the paramedics said it wasn't dangerous, I'm not convinced.
