You must consult an orthopedician and a rheumatologist, along with a dermatologist for psoriatic arthritis.
2. Is there any connection between the severity of psoriasis and psoriatic arthritis?
There is little connection between your psoriasis severity and psoriatic arthritis severity. Having a severe case of psoriasis does not necessarily mean a person will have a severe case of psoriatic arthritis. A person could have few skin lesions, but have many joints affected by the arthritis.
