I have been on accutane for a little less than a month now and I have a rash on my hands that has been gradually getting worse and is starting to sting. I am taking 10mg in the am and 40 mg pm as prescribed by my dermatologist. The rash is not bumpy at all, at touch the skin is smooth so this rash is completely under the skin. Is this normal? What can I use to reduce or get rid of this rash? I have also been experiencing severe back, knee and ankle pain, not sure what to use ?
