Sciatica involves nerve damage usually. I only have very little scalp psoriasis but have terrible PsA.

Hi @A MyPsoriasisTeam Member

Did you mean Psoriatic Arthritis ( instead of Sciatica? )

Because Psoriatic Arthritis ( Psa ) and regular ( scalp, skin and nail ) Psoriasis ( Pso ) are all part of the same family.

They’re connected as they’re all part of Psoriatic Disease ( PSD) which is a familiar of immune-mediated, inflammatory conditions. This may help explain the differences.

Sciatica is a condition that involves nerves and sometimes discs in the lower back..
