I have been suffering from osteochondrosis for 7 years. I feel it especially in the cold season - when I get a little cold, my back immediately starts to hurt. During one of these periods, my daughter brought me Flekosteel. About 15 minutes after applying the gel, the pain began to subside. Now I always have this gel in my medicine cabinet, I still use it when my joints start to ache when the weather changes.
