hi dear
yoga really help u to eradicate this problem.the best devices for this problem are laser and ultrasound and then TNS or IFC.
all the best

Thats something to think about. The lazer devices appear to be too expensive to buy for home use. Ill stick to the yoga and perhaps experiment with an ultrasound device for the tighter spots in the upper back. Thanks for your suggestions.

Just wondering, would it be beneficial to wear a TENS or IFC device continuously during periods of sitting to slow down the rate at which the muscles of the upper back become become tighter/uncomfortable?
