Do you have arthritis or know someone with arthritis?

I was recently diagnosed with arthritis & I have a muscle spasm that causes neck pain. I went to a chiropractor & he was able to help with my neck pain, but now my arthritis is bothering more. They sold a drink with glucosamine, chondroitin & MSM:

I don’t want to keep on taking pain killers & actually sometimes they don’t help, so I bought vitamins at the store with glucosamine, chondroitin & MSM which was cheaper than the drink (but my prescription for pain killers is free since I have no copayment). Do you know if these vitamins will actually help my arthritis or am I just wasting my money?
I was asking about the weather because sometimes I hear people say they can tell it’s going to rain because their bones ache, but I myself don’t notice that, I hurt everyday. I just was wondering why people say it if it isn’t true.
