Mary Ann,..Voltarol and Voltaren at a glance appear very similar,..reading the uses of both the only difference i can see is,
Voltaren reads- for the treatment of Hands,..Wrist,..Elbow,..Knees,..Ankles and Feet,..to treat pain caused by Osteoarthritis.
Voltarol reads-----------------------------------The Same As Voltaren,..except it mentions to treat pain caused by Rheumatism.
both contain Diclofenac.
Gosh $75=£68 for a Tube of Voltaren is very high,..how big a tube is that?,..well done finding it for $10 a Tube from Poland
My Voltarol costs £10=$11 for a 30g Tube here in Ireland,..i must check the price in Poland
