Hello, Your symptoms suggest that you are suffering from peripheral neuropathy. While diabetes is a frequent cause of neuropathy, it is not the only cause. Nutritional deficiencies (B-12 and folate), chemical exposures, pressure on nerves, or medications like chemotherapy medications etc. can also cause neuropathy. You must consult your doctor to find the exact cause of your problem. In case your symptoms are due to VIT B 12 deficiency or folate deficiency,injection NERVZ would help you but in case it is due to diabetic neuropathy,then it would not make any difference. You must then consult your doctor and get yourself tested for the presence of diabetic neuropathy. A variety of tests, including electromyography (a test that measures the response of muscles to electrical impulses) and nerve conduction studies (a study of the flow of electrical current through the nerves) combined with clinical observations may help a physician rule out other possible causes of pain and diagnose neuropathy.  Although there has been considerable advances in the understanding behind the development of diabetic neuropathy but their treatment has been limited. Along with a meticulous and tight control of blood sugar levels,treatment is aimed at reducing pain and other associated symptoms. This is achieved by use of antidepressants like DULOXETIN ,use of anticonvulsant like PREGABALIN and a long acting opioid like TAPENTADOL. You must discuss with your doctor to use these drugs singly or in different combinations. Thanks
