Day starting out badly

I've been up since my normal time of around 5am and took all my meds, including the pain med. for my leg but right now I am in so much pain.  I don't know if it's because of the chair I'm sitting in as normally I am on my laptop sitting in my recliner.  I have my Nerve Test tomorrow morning and am very nervous about it because of all the negative comments I have read about how painful or uncomfortable the test is.  They say the test could last up to an hour - that's going to be a long time to have to try to tolerate the pain I'm already in and the pain from the test, that and I have to keep moving my leg to try to get it comfortable so I'm sure they are going to have a problem with that.  Going to try to not worry so much today about the test tomorrow and am going to try to not be so irritable and cranky today.
