I've Been Having Pains Mostly In L Arm And L

I've been having pains mostly in L arm and L leg feels like it's in my muscles to my bones along with my sciatica nerve so I have numbness and tingling at times but I do have carpal tunnel in my L wrist. I've been having the other pain in my leg and arm for at least 8 months along with the sciatic nerve pain. I also been having pain in my lower back and at times in my upper back. Could rheumatoid arthritis cause these Symptoms
