   Free text: I actually want to correct yesterday's report. I had lower back surgery a few yrs ago and started to have the same back pain I had before my surgery. It started about 12 hrs after my 2. Shot. Suddenly I had lower back pain again, as if a knife was stabbed into my left buttox with pain down my left leg, just like I felt before the fusion of L5/S1 about 4 yrs ago. I am taking Ibuprofen since then and it's slowly getting better. I have no fever, no chills, no other issues. Only pain at injection site and quite some pain in my lower back. As if that was my weak spot in my body and this virus/microorganism manifested itself there. I can function and do my daily activies but it is painful. Lets hope this will cease within the next few days. I can hardly sleep at night. Thank you for the follow up.

   Free text: Today my back started to feel a little better. Now more like a burn down my left leg and the feeling of a sore buttox muscle. Still taking Ibuprofen but back pain is slowly getting better. Other than that I am well. Thank you.
