Anyone else have problems? I have been diabetic type 1 for 40 years . A year ago I started getting tingly lips & numb tongue as well as burning soles of feet after my injections. This has since progressed to palpatations and a feeling of permanently going low. I have finally got an immunology appointment this week but wondering if anyone else had probs & what they did? This has happened with novorapid regime and now porcine insulin too.
