An occasional complication of dry skin and itching is secondary bacterial infection. Infections may be mild and resolve spontaneously or may be more severe and necessitate antibiotic treatment. Severe itching leads to repeat scratching of lesions, hence the "itch-scratch- rash -itch" cycle. Because of the persistence of this itch-scratch cycle, the skin may become much thickened in these areas from rubbing. Repeat skin rubbing in the same area may lead to two localized chronic skin conditions called lichen simplex chronicus (LSC) and prurigo nodule.
My itching started 10 days after giving birth to my son. my obgyn said it was not Pupp because “Pupp only occurs during prgnancy.” So I went to my family doctor and he said he had treated 3 cases of Pupp after delivery and he was sure what I had was Pupp. He prescribed prednisone for 7 days and the itch went away after day two. However 3 days after i finioshed the dosage, the itch came back. Its been two weeks since then and I am still itching. Hot compresses before bed seem to give me enough relief for me to fall asleep.
It seems strange, then, that allergic reactions to corticosteroids actually occur—especially since these medications are used to treat allergic reactions. While severe allergic reactions to corticosteroids are extremely rare, they do in fact occur. Most allergic reactions to corticosteroids are less severe, however, and result from the topical formulations—occurring in up to 6% of people. Allergic reactions to oral or injected formulations are rarer, occurring in less than 1% of people. Causes of allergic reactions to corticosteroids may be due to IgE antibodies , or as a result of delayed-type hypersensitivity reactions caused by T-cells (a type of white blood cell).
