I HAVE THAT ON MY LEGS, BUT NOT AS BAD. My doctor said it was psoriasis, but I don't think so. I thought it was caused by my
stellate ganglion block that I had in 1993. You might not have noticed the hair loss on the legs like I notice. I had hairy legs, but now there are bald spots on them. I live in Michigan and It gets worse when it starts to get cold. I have to put tons of lotion on three or four times a day. I use the cheep stuff, Suave Skin Therapy. But after winter starts I don't need so much and in spring none at all. The legs itch like hell, but I know better not to scratch. Yours looks like your using oil which makes them soft but that made mine worse. The oil does not allow the skin to breath. Try a different lotion. Was wondering where you live. I am thinking moving to where it does not get so cold.
