How to Identify, Prevent and Treat Poison Oak, Ivy and Sumac From WEBMD “What causes a poison ivy, oak, or sumac rash? The rash is caused by contact with an oil (urushiol) found in poison ivy, oak, or sumac. The oil is present in all parts of the plants, including the leaves, stems, flowers, berries, and roots. Urushiol is an allergen, so the rash is actually an allergic reaction to the oil in these plants. Indirect contact with urushiol can also cause the rash. This may happen when you touch clothing, pet fur, sporting gear, gardening tools, or other objects that have come in contact with one of these plants. But urushiol does not cause a rash on everyone who gets it on his or her skin. What are the symptoms of the rash? The usual symptoms of the rash are: Itchy skin where the plant touched your skin. Red streaks or general redness where the plant brushed against the skin. Small bumps or larger raised areas (hives). Blisters filled with fluid that may leak out. The rash usually appears 8 to 48 hours after your contact with the urushiol. But it can occur from 5 hours to 15 days after touching the plant.1 The rash usually takes more than a week to show up the first time you get urushiol on your skin. But the rash develops much more quickly (within 1 to 2 days) after later contacts. The rash will continue to develop in new areas over several days but only on the parts of your skin that had contact with the urushiol or those parts where the urushiol was spread by touching

Hi

I have several different rashes on my body.

On my neck I have standard dry skin/eczema that has spread onto my face. I am treating this with moisturiser at the moment and it is healing ok. Just looking for further advice on this.

I also have little bumps on my fore arms, that are now spreading to my upper arms. They look like "goosebumps" that you get when you’re cold, but are only in little patches, the size of large coins. At first they were red, but after Hydrocortisone cream and moisturiser, they are now just skin-coloured, but rough to the touch. Any advice??

Any comments and suggestions appreciated.
Merry Christmas!
Could I be suffering from Keratosis Pelaris?
The symptoms seem to match the rashes on my lower arms. Any suggested treament for that. It is said to be recurrent with no cure…
