Hello. Thanks for writing to us at healthcaremagic These sites i.e hand, elbow, knee etc are trauma prone sites and psoriasis commonly involves trauma prone sites. Therefore, in your case, there seems a direct relation between psoriatic involvement of these sites and your job profile. Emollients form an essential part of the overall management of psoriasis and should be used twice daily at the involved sites. Specifically for the psoriatic patches, I usually recommend twice daily application of topical potent steroids e.g clobetasol propionate ointments with Or without salicylic acid. I strongly suggest that you visit a specialist in your region for an assessment of the severity of psoriasis and appropriate treatment. Moreover since steroids are prescription products therefore prescription is mandatory. Regards
