Six months ago, I had a sudden feeling of skin numbness in my legs and a feeling of inflammation in my toes and soles of my feet. That lasted for 4 weeks and, in the space of a couple of days, went away. Unfortunately, it then moved to my right arm and hand. For 5 months, now, the skin on part of my lower right arm feels slightly numb and my fingers feel inflamed and the tips of the fingers feel highly sensitive. Because this went away in my feet, I am hopeful that it will also go away from my hand. Is this likely to happen or is this something I will have for much longer?
