Twice a week, I have the honor of working with senior citizens from age 62 to 92. They receive the benefits of the chair massage given once a week or every other week. A chair massage is 25 minutes long, covers the full back to the hips, neck, shoulders, arms and hands. The areas where arthritis resides frequently.

Yes it can by increasing blood flow to an area.

Absolutely. Manual lymphatic drainage, has been shown to reduce both swelling and pain and it supports patients with arthritis.

For arthritis I recommend paraffin wax dips for the hand, fingers feet and toes. Or bushed on for the back, elbows, knees and where you can't submerge into a bag full of wax.
As far as massage is concerned, gentle Swedish massage is the best for arthritis, as long as you don't have a painful flair up.

Yes, 100%
Before I had my hip replaced I tried everything from NSAIDS to Chiropractic and the ONLY thing that made me feel more comfortable until I had the hip replaced was Massage.

Yes it can temporarily provide some relief
