My boyfriend has arthritis. He s been lifting weights for 40 years and is in great shape, however, lately if he goes in a restaurant & it s cold, his legs freeze & feel numb. He s been going to a chiropractic because of the numbness issues, but that doesn t seem to be working. He had an epidural, but that didn t work. He s at wits end that no one can help him. Any suggestions of what king of specialist he should go to? I hope to hear from you. Thank you, Roseann
