What Does Pain In The Shoulders, Arms And Feet Indicate?

I recently traveled to new england for a week. upon returning i started having pain in my shoulders, arms , hands, feet and back. i took tylennol and ibrofin. with little relief. the pain is so bad at night, i can t even roll over in bed. i visited my doctor and he performed blood tests which have not come back yet. the onset was so immediate, i thought that maybe i may have lifted something too heavy. so now im waiting for the blood test to come back to determine if i may have RA or ostro artritits. Im thinking i may have some kind of virus attacking my body. please give my your input as to what you may think regarding this. thank you
