Fungicros Cream Health Feed

Medical history- i'm 56, female, diabetic since ten years approx. My fasting glucose remains around 240 while pp around 290. I've been taking medicines (galvus met 50/1000 mg and amaryl 2 -both bd) since long, but my sugar levels didn't show any significant changes and hence my doctor added vogliboz 0.3 tds to my regime (two weeks back). Last, I got my glucose levels tested yesterday and they are still the same, only a mild reduction registered. I walk 3-4 kms daily in the morning, apart from that I don't have any other physical activity on schedule. My last month's thyroid report- (t3/t4-normal tsh-low-0.21 iu/ml) i'm currently on thyroxine 75 mcg as well. Main problem- my toe nails have been showing an inward growth since an year or two, which has now started causing pain. I feel soreness in my left toe almost all the time, while it hurts insanely whenever it contacts any hard surface. Nailbed has become so thickened, that it is not possible for me to cut the toenail myself. What should I do to curb this problem? Also i'm having a little pain in my heels and ankles lately, but it is not much significant. And my doctor told me that I will need to switch to insulin, if my sugar levels remain the same after two months. Can I not be treated with oral drugs anymore?
