A serum creatinine of 1.62 indicates reduced kidney function, so your current medicine may need adjustment. The best diabetes medicine to help control blood sugar while protecting the kidneys will likely be an SGLT2 inhibitor (such as dapagliflozin or empagliflozin) or a GLP-1 receptor agonist (such as semaglutide or liraglutide), but your doctor should assess and prescribe the appropriate treatment.

The prickly pain in your fingers is likely a symptom of diabetic neuropathy, often caused by nerve damage from long-term high blood sugar. Your fasting glucose level of 150 is still too high, so you should contact your doctor promptly to adjust your medication and help manage your pain and blood sugar.
