I have had a rash on my hand and wrists close to 12 months, started of itchy, the last three months it has become very dry, lumpy, thickening of the skin on the affected area crusty very itchy at times cracks and bleeds. Biopsy result Lichen planus waiting to see a dermatologist, thus far none of the skin medications have helped. Upon application of medication there is a softening of the lesions however if i don t apply it every four to five hours it once again turns to sandpaper, please help.
