That is only if pain is caused or worsened by the device which never occurred and will never occur. Chronic pain conditions are regularly monitored by doctors regardless.
Not sure, I don't have the instructions....i went to the doctor and have a small meniscus tear....tried painkillers first, then a shot....now the BIEL product....BIEL product seems to be the best so far....Doc is for trying anything before surgery...even mentioned glucosamine....
Good idea ddls Checked my supply (recent version) : nothing on the box .... except for : see product insert for more information And inside a leaflet with warning : if pain or swelling persist or worsen, discontinue use and seek medical attention immediately
