Hi, thanks for posting your concern in the HCM. Your condition suggests that you might have got ophthalmologic complication of diabetes and neuropathy. Diabetes, in long term with or without poor control can produce several ophthalmologic complications including non-proliferative and proliferative diabetic retinopathy. The black floaters in a known diabetic patient with poor control can suggest vitreous pathology, retinal tear also. Regarding your skin sensations, they are most probably due to diabetic neuropathy. A stringent control of diabetes is definitely the need. You also need to check a complete blood count and CRP to rule out any infection that may have caused this fluctuation of blood glucose. Any history of fever, leg and ankle swelling, feet discolouration are also required to rule out other complications of diabetes. Blood test for HBA1c will provide you with information regarding your long-term glycemic control. You can have a vitamin supplement containing B1, B6, Pyridoxine, antioxidants etc. that can for the time being give some protection against the neuropathy. And, my final recommendation is that you consider the situation as an emergency and consult your local doctor and a consultant ophthalmologist. If required, you can write back to us with above mentioned reports and retinal and posterior segment examination report by an ophthalmologist. Regards and best wishes for your good health.
