Yes there is something you can do about ED---Find a clinic that uses a vasodialtor medication that you use to inject yourself into the penis that can cause the blood to flow into the penis and get erect--within minutes. One on the drugs used is PGE and just causes the penis to get full of blood. When the medication is metabolized the erection subsides.
I know it sounds crazy but I have injected over a hundred patients and have had very good results.
I use a very fine 31 guage needle and the patient hardly knows it---and they do it to themselves with great results.
You can ask a urologist if he offers this in his practice or can refer you to someone that does cavernosal injection therapy. Read about PGE.
Hope this helps--David
Have you had your testosterone levels checked?
Does Levitra always give you a headache or does that vary with your blood sugar level?
Either way, tightly controlling your blood sugar is the best way to help the ED. See bloodsugar101.com for more info.
