Hi! as you have mentioned your complaints are basically hypersensitivie and autoimmune by nature. these kind of problems are caused by altered sensitivity and susceptibility to the envirionment (may in external or internal). being a homoeopath what i can say is that homoeopathy is most probably more suitable to treat such condition as it treats the person, and not the disease. As you have taken Homoeopathy in past there may be 2 things, 1) As psoriasis
is being known for its recurrence, it may have come back but this time in less intensity and in less area of your body. 2) your homoeopath needs to rework on your case, make fresh case taking and see how things unfold. I dont think other modes can give you lasting results.
Regards and take care,
Dr. Mikin Jain (m.d.) homoeo.
