Hello, I have studied your case. As per your symptoms muscle pain can be there because early spine degeneration due to diabetes and associated osteoporosis. His pain may be due to diabetic neuropathy which is difficult to get cured. Lyrica will help him; you can start as required consulting your doctor. Physiotherapy like TENS and anodyne therapy will help him. If not relieved then epidural injection can be given for long term pain relief. You require diabetic control to control pain. Diabetic diet which you can follow - that you need to avoid fatty, bakery and high carbohydrate diet. And you need to focus on high fibre, moderate protein and high mineral and vitamins in diet. You need to avoid Sugar – includes soft drinks, fruit juices, fructose, sucrose, agave and the obvious cookies, cakes, etc. Starch – both potatoes and rice are high in starches; which means they are high in carbs. Grains – especially wheat (gluten) in ANY form; flour, pasta, breads, crackers, cakes, Tran’s fats, hydrogenated oils - including corn and vegetable oils. Ditch the canola oil and bring back the real butter! Cereals – All kinds. Legumes – including beans and peanuts (peanuts are technically a legume and not a nut). Pasteurized milk High Carb Fruits - especially bananas and pineapple. High Carb Vegetables – avoid potatoes. Hope this answers your query.
