Hi Caroline,
I am having my trial as we speak. I have leg pain and my trial is working well I have full coverage of my leg, it even covers my left side abdomen.
If you have any questions please ask, I have time on my hands as I am just laying in my hospital bed. In Oxford you get the trial on the Thursday then they internalize on the following Tuesday. I am on weird timings as I was slotted into the system out of sync.
