I'd go for further tests and more information. Some of the symptoms could be from high or even low BG and as suggested could be blood pressure - or various other unrelated things.
One thing which may be related to diabetes (both types) is connective tissue and joint problems, such as Frozen shoulder, carpal tunnel etc. BG control will make these less likely over time but they will almost certainly need treatment, even if just antiinflammatory ointment. I used to get problems with my shoulders, not quite frozen but painful and limiting movement, which seldom occur nowadays.
