I have not had any blocks..I know they are coming,though

I am in the same place per your question. The thought of needles

I have to give blood at my PM appts., hurts for 2 weeks afterward.
I have used the Lidoderm patch and the Flector pain patches. Flector is a lot more expensive, as it has a stronger dose of pain killer. I find relief in both patches. I have not been able to wear either one the 12 hrs. that script indicates. I can take about 4 hrs. at one time.
I have noticed that the Lidoderm patch stays in place better than the Flector patch. The flector patch is thicker in form.
