Psoriasis relapse. Requesting Dr Sameer Vermani's help

I have had psoriasis since 2003, I think. It was then in scalp. In 2006, it started in fingers and then in legs and elbows. I went to an Allopath who gave me Dipsalic which I had used on and off to control the patches. Meanwhile around 2012, scalp started scaling heavily, like severe dandruff. In 2014 August I had a virulent attack of acute Urticaria with severe rashes and itching which started with my hands and then spread all over my body. No anti-allergy tablet brought even the mildest of relief. Within a month I had fever, itching, scaling from all over my body and swelling of hands, legs, ears and face. My entire body turned several shades darker. The ankles of my leg were black. After trying 4 doctors, two of which we were homeopaths, I went to another homeopath whose gave me 3 medicines – Psorinum, Petroleum and Sulphur which got rid of fever, scaling and swelling in 2 days. Itching continued. He changed Suphur to Apis and itching stopped. I was totally free of psoriasis. He stopped Apis. My skin started getting lighter very slowly. There were sporadic cases of rashes (eruptions, as if bitten by bed bugs) which went away as soon I took Apis. The doctor kept me on the first two medicines (Psor and Pet) for more than 2 years now. Now suddenly psoriasis is back hugely in legs and on the scalp. The doctor tried to change the medicine and then put me back on the same (Psor) but there is no change. He has increased the dosage to Psor 10M but no impact still. Dr Vermani, Please help. We have seen how deftly you have handled another psoriasis case.
