Hi Goldie,
Since you mention the 30 yrs of office work , I'd like to suggest you read on our Thoracic outlet syndrome forum (TOS) for short...
here's the link to the useful sticky thread tone of info-

Even if symptoms don't fit for you- many of the therapies & tips are good for anyone.
Pec minor pain/tightness
ring/pinky finger sx
neck/shoulder pain /tightness
Do you have a forward head/shoulders posture??
Often happens when long term desk/office work.
If so it closes down & crowds the area that provides blood flow & nerves to arm & hands.
