About arthritis. There is any way or any medication to help relief the pain. Cause I have arthritis with severe spasms of my right leg.?

Depends. You should see your doctor for evaluation in person. Arthritis is talking about bones and joints, spasm is talking about muscles, so there may be something else going on and you need to be seen in order to sort this out.
Leg spasm. "arthritis" and spasm of leg can be uncomfortable, but can be symptoms (or precursor symptoms) of a deep venous thrombosis which if not treated can kill by launching clots throughout the body. Do not neglect the problem and see a doctor to find the cause of the problem. How long has it been bugging you, increasing symptoms? Any one-sided swelling and other leg not swollen = danger.
