This type of arthritis is sensitive to weather and to seasons.
It may or may not be reactive to food. This may or may not be an individualized thing. Much is being learned.yet. Interestingly enough, people with PsA are much more likely to suffer "Gout," which is usually food related; however, many of the Gout cases in PsA are deemed "idiopathic."

I find October is the month when big flares start up for the winter. My rheumatologist says all of her PsA patients start calling her within the same week.

i have found the immune reaction is often triggered by stress.

There is a correlation with asthma. Both ~Christina and I also have asthma. Poor ~Christina has much more severe breathing issues than do I at this time.
I do have to take an occasional ride to the ER by ambulance due to exacerbated asthma.(Especially if I ever catch the flu.)

This condition can be excruciatingly painful. I am on morphine every day, all day long. I also , often, have to add prn dilaudid. This, in addition to NSAIDs and the immune-modulating drugs.

When I was diagnosed, it was incredibly difficult to find out anything about PsA. Over the past 10 years, this has changed after much more research has been done. Doctors now recognize the severity and the potential complications, like asthma, heart disease, etc.

I can start to ramble about this when asked. I might also ramble when not asked.

I am so glad you are feeling better!

Thanks for caring!
