Could The Muscle Spasms In Arm And Back Be Due Mental Stress?

my gma just died tonight and my mom just lost my dad a year and a half ago. shes overweight and 50 yrs old and came to my in extreme pain of her left forearm just below the elbow, complaining of muscle spasms, heating pads helped. then an hour later she had back spasms and had to sit for awhile. my question is could these be signs of a stroke or just related to stress? what should i do? please help
