Hi welcome to Health care magic forum. There are so many newer drugs for arthritis pains. Pragaboline and methyl cobalamine are expected to minimise the pain perception. Injection of combination of vit b1, b6, and vit b12 along with other analgesics is reported to minimise or cure the pains of arthritis.
Metho trexate is a recommended drug for rheumatoid arthritis
. So with these supplements you can continue with your doctors treatment.
Besides i advise you to follow some diet recommendations as avoid taking more of potato, other tubers, tomato, cauliflower,coconut, egg, chicken, and sea foods as these tend to increase the pain in arthritic patients.
Wishing for a quick and complete cure of the disease, and thanks for calling.
