How Can Erectile Dysfunction Be Treated While Dealing With Diabetes, High Blood Pressure, Kidney Disease And Bipolar Disorder?

I am 63 years old and have had Type II Diabetes since my mid 40 s. I have a small dark spot of muscle (4%) on my heart that is not in a bad location. I suffered a stroke 2.5 years ago which affected my balance. Diabetic neuropathy in both feet, a DVT and Charcot Syndrome of the left side has caused me to stagger badly. I take several medications to control: diabetes, high blood pressure, high cholesterol, Type II kidney disease, pain, ADHD and bipolar-disorder. My labs look good now except for low sodium that I take another med for. I have changed many bad habits and improved my diet; I have gotten off the couch and started to walk again. I am up to 9 miles a week and feel much better. I am working up to my old aerobics program goal of 16 mile per week, in 4, 4 mile sessions. If I do well, I ll add another 4 miles per week. I have had ED for 10 years. Viagra stopped working well after 2-3 years. I ve also been diagnosed with a benign urinary obstruction that slows urine flow. Now to my question: with this background, what can I do to try to offset the ED? I have read that there is a self-administered injection for the penis that works well. That solution doesn t bother me other than what the cost may be. Other than kicking me in the behind for letting myself slide so low, what do you think?
