know someone, a friend, who knows....but, which kind of arthritis? There is no cure, can only medicate.
diclofenac is a anit-inflamatory...watch out for kidney damage. Get a lab every 3 months to check kidney function.
methotrexate...commonly used for cancer patients...cheap and may work but have heard it's probably not good to take.
Leflunomide...Arava...use along with other arthritis meds...by itself not so great but with other meds works good.
Enbrel...works well with Leflunomide.
the only creme my friend knows about is a prescription diclofenac creme. Works only on joints and not on muscles.
I bet your friend will have to experiment with some other bullship prescriptions to find the best relief...at least that's what my friend says. He is familiar with RA so not sure if these above drugs would work as well on the other kinds of arthritis. Has your friend been diagnosed by a real doctor?
