Psoriasis which is an autoimmune skin condition can be hidden and individuals are often unaware that the cause of joint pains lies in this small psoriatic patch.
A good Rheumatologist will always give time to his patients and will look for hidden Psoriasis.
Psoriatic arthritis responds well to treatment and the drug used for arthritis can clear all the skin lesions.
If you get persistant dandruff and such scaly skin lesions along with joint pains, you can have psoriasis with psoriatic arthritis.
Meet a Rheumatologist.
