Not every person who gets psoriasis also eventually finds themself with arthritis. Of those who do, there are a number of ways one can go with treatment.

1. Biologic treatments such as Enbrel are done with periodic injections. The problems with some biologic treatment include lowering the immune system and side effects.

2. Diet can help some people with both psoriasis and arthritis. This technique is really trial and error.

3. Tar and LCD creams can help both psoriasis and arthritis in my experience. For example when I've worn gloves with black medical tar, my finger joint with arthritis became less swollen while the psoriasis went into remission the more days I wore the tar 8 hrs per day.

4. There are treatments by pill that target psoriasis and/or arthritis. Some work, but again side effects are a concern.
