Neuroma is a tumor made of nerve tissue. Capsulitis is inflammation of the joint capsule, typically in the shoulder.

Capsulitis

adhesive capsulitis of shoulder (i.e. frozen shoulder)

It's a serious medical condition involving the connective tissue surrounding the glenohumeral joint of the shoulder. This becomes inflamed and stiff, restricting motion and causing chronic pain.

We've had good luck with a diagnosed case of pretty severe capsulitis of the second toe using insoles from naturalfootgear.com (we are not affiliated with them), after trying homemade toe pads for Morton's toe made from the instructiuons in the heal-your-Morton's-toe book (can't remember the title). The home-made toe pads did work pretty well, but they always had to be remade as they wore out, and so were never exactly the same each time. The insoles from NF are the 6.5mm ones, specifically for capsulitis, and the people on the phone there are super helpful and into it. (They also have shoes and toe spacers, which we also might be trying.) Also using massage, stretching calf muscles, never walking on hard floors in bare feet. The pain used to be so bad it was hard to walk at all, and now it's almost completely gone away.
