I have pityriasis abla on my arms now for about two years. I have gone to the dermatologist and they prescribed me locoid lipocream but I feel that it hasnt helped. I have eczema and asthma which I know are associated with this disease. But I m wondering, since I had scabies as a baby, does it have to do with my skin now? And, can this disease spread down my arms further or what other treatments can I do?

I have been diagnosed with pityriasis rosea. Have had a horrible rash covering most of my body for 2 weeks now. Skin is extremely dry and I have recently noticed a distinct odor originating from my skin. Is the odor common and how can I get rid of the odor? I know I pretty much just need to wait for the rash to go away.

I have a big black/brown circle shape on my back but it don t hurt me in any way though. and there is also white patch like thing starting from from my back right shoulder covering my right arm and on my right chest. my right hand is not completely affected by it but it looks strange as some part of it is normal skin colour and some is white. its kind of mix and hardly noticeable from some distance. I did some research on Google and I m confused what it is and as far as i think its pityriasis-versicolor but I m no doctor so I m not sure. I didn t had this since my birth but its on body for more than 15years if i can remember. I m 23years old right now and I m from south India where temperature is mostly hot and i usually sweat a lot even if i do a small work.
