Hello Doc.found Out Recently On Line My Medical Records Show

Hello Doc.found out recently on line my medical records show diabetes 2 for 6yrs. Never no physical or noticeable health problems? Had a Lumbar Decompression in 2013. That worked but can't do as much as I was before,I understand that. Last year had bad blood test and detoxes off meds.Started with very much pain and entire body felt like red ants were stinging me 24/7.emergency room no help.(fast forward) Sciatic nerve inflamed about 3to4 weeks ago.Left foot gets in pain and a lots of numbness on many occasions but not always .my question is what is causing my foot problem? Have been searching and found out today could be blocked blood vessels .Asking for help that's why I gave a history lessen.
