My wellbeing has gradually worsened for the last couple of years. I used to be full of energy; working out 5 times a week, whilst making sure to get enough food, rest, and restitution between the days. My program was a mix of yoga, interval training, and resistance training. Then, gradually, my energy drained away until I had nothing left to give. I am a 27-year-old caucasian male. Besides Type-1 diabetes, my health is good (at least to my knowledge.) My HbA1c has been stable between 6.3-6.7 for the past ten years or so, and there have not been any diabetic complications or emergencies for the 20 years I have been a Type-1. I have used a pump for 18-19 years, and I am still not using a CGM, nor do I carb count. (I have never needed to.) In fact, I have never been much ill at all. So my (quite) recent cocktail of symptoms has me a bit worried. It started around 6 months ago, with this... strange, metallic slow burn in my lungs, beneath the sternum. It smoulders like a shot of strong alcohol, or when you push yourself to run for too long. It reminds me a little of having high blood sugar; that "fruity" sensation up your lungs and throat, the stiffness of joints and muscles, and the feeling of dehydration. However, my glucose levels are fine. My vision is blurry, my memory and thinking are fogged, my neck and shoulders are painful; sometimes throbbing, my hands and feet sometimes turn a purple hue and swell up, and, without my temperature rising, I have frequent bouts of "fever." My eyes burn, light makes them water and burn even more, my head is throbbing, and I FEEL burning warm; yet, the temperature remains normal, though slightly lower than average. My whole system seems... wrong. I have had several trips to my GP for testing and consultation; the CRP showed no sign of infection, lymphocytes acted normally, and vitamins were not low. Heart-rate and BP are fine. No signs of diabetic neuropathy either. The only thing found was slightly elevated protein levels in the urine, and a little whiteness on the tongue; not uncommon for a Type-1 diabetic. So my GP eventually brushed it off as "just a bit under the weather." I am at a loss because it affects my day-to-day living. Does anyone have some light to shine on my situation? Anything would be appreciated.
