Hi there, Thanks for your query. Firstly, Metformin has brought down your blood sugar to within desirable range, though the morning (empty stomach) blood sugar is still high. There is thus, a need of increasing the dose of metformin; or, addition of another drug. Metformin is detoxified and thrown out of the body predominantly by the kidneys. Hence, mild liver damage in not a contraindication of stopping metformin. Lastly, it is probably a coincidence that you developed blisters on the hand after you started metformin. These blisters are probably viral and need a course of anti-viral agents. Consult your doctor and apprise him of my opinion. I am certain that he will agree with me, order required tests, and- based on the reports- will prescribe suitable/modified treatment as advised.
