Hi I have pain in upper back. If i do some activity with both hands I feel tingling numbness from mid back to left shoulder. I am a dental hygienist by proffession. Itmakes it really painfull to work. This is been chronic issues I have suffering from it for some years. My dr has prescribed muscle relaxents and pain killiers. But i cant take it regularly as I work really early in the morning. It comes and goes but when it flares up i am in excrutiating pain.
Dear friend I understood your problem.it may be spasmodic pain over the upper back, and it spreads to your shoulder due to over activity of back muscle. So you have to apply ice on the upper back, and it reduces spasm.three times per a day for 15 days. If possible you can take rest, use of very less amount of your pain full arm and shoulder joint. If pain will not be gone than you have to go for physiotherapist. Take ultrasound therapy, tens.
