I think you might be reassured by a blood test/GP consultation.

Renal deterioration is relatively symptomless, until severe, blood test is gold standard here, and a very reasonable thing to ask for.

Weakness in legs should be evaluated without delay, as should persistently frequent headaches.

But, they do fit the side effect profile of rosuvastatin (Crestor)… have you thought of this?

Good luck @borderter , do let us know how things go.

Edit to add:
Lifted from NICE
Recommendation:

In adults with type 2 diabetes, review the dose of metformin if the estimated glomerular filtration rate (eGFR) is below 45 ml/minute/1.73m2:

• Stop metformin if the eGFR is below 30 ml/minute/ 1.73m2.
