C/P,back pain: May be reflux, gastritis. Trial of ranitidine/prevecid ? May be muscle spasm (doubt it is heart) Back pain may be poor ergonomics/computer position/ activity. Need to sit straight with elbows at 90 degrees, feet on floor and screen at eye level. Take a 1 minutes break every 30-45 minutes to stretch and shake out arms, shoulders and back. May need seat cushion Discuss.with MD/ urgent care this wk
