Swelling after humira in knees.

Hi. I am new and appreciate everyone sharing their stories. I have had psoriasis since late teens. The dermo kept saying it on my scalp was dry scalp and until it spread to my ears I was finally diagnosed in my late 20's. it started to spread to elbows then shins and face. I have tried steroid creams and finally broke down to try humira after I was diagnosed with psoriatic arthritis which impacted my hips, knees and joints. It was working great although the weight gain was dramatic. 20lbs in a year. I started having memory loss so they stopped it to do testing as a precaution. Everything was ok but in the time I was off it I seemed to lays get sick. They warned on it I needed to be cautious but I was the opposite. Never sick on it but when off every time I got even the common cold it was severe. It was as if my immune system never came back. I recently the past few months developed swelling in my knees. First the left then the right. No mobility. Couldn't walk. Referred to a knee dr no tears so back to the dr and drawing board. Don't want to be on the steroids but since off humira they are necessary to stay mobile. Being a mom of two active boys need my legs. Want to go the natural route but can't stay normal long nought. Read up on boswelia extract and the omega 3. Good info people are sharing. Has anyone experienced what I am after being off humira and any luck with ths herb long with omegas? Any feedback is appreciated. Really am sick of medicine.
