Query regarding skin problem.

3 years back I had psoriasis problem appeared just on feet and elbows started with itching and ended up with small black patches and mild redness around. When I consulted a dermatologist he prescribed me lorinol 10g for itching, a cream to apply called "mometasone furoate and fusidic acid cream", a D-vitamin tablet and multivitamin tablet "VX-FORTE" on my third consultation. Due to the prescribed treatment psoriasis problem reduced but now suddenly it got flared up spreading to testicals balls in my private area. Initially it started with too much itching and ended up with redness with skin quite bulged. This time it is quite painful.I tried booking appointment with the dermatologist but appointments were available after 3 days. Meanwhile I applied the above mentioned cream and took the lorinol 10mg tablet and appled also the moisturizer named "Dermoys" after psoriasis cream as prescribed before in my case. Is it appropriate what I did before appointment based on previous medication?
