Welcome to health care magic
I can understand your situation. I appreciate your effort to seek online support.
Dermatograhic urticaria is a condition which involves inflammation of skin when it is scratched or rubbed. It is a type of allergic conditions. It mainly involve young ones. Its treatment involves antihistaminics.
Psoriasis is a chronic autoimmune disease
and it needs long and continuous treatment. I advise you to consult a qualified dermatologist
for proper evaluation and ,management. Meanwhile, try doing relaxation techniques
like deep breathing, yoga or meditation
to alleviate stress and anxiety.
Hope it helps
