I was giving myself a lantus injection every evening for blood sugar and eventually scale back until the doctor said I don’t have to take it anymore because my A1C is good. What I would like would be an injectable pain reliever for my occasional migraines. They have them but I have to get it approved through insurance. There are also nasal sprays to administer a quick acting pain relief.
For my tension headaches and occipital neuralgia I’d like a quart of novocaine.
