This is my first time using a CGM. I just put my first sensor on yesterday. Ever since, it has been giving me false and very low readings. Also, the arrow is always in the same position, pointing straight to the right. Never shows the arrow up or down. These levels range between 23 -49 unit differences in between the reader and my normal finger-stick blood glucose.

Will this eventually sort itself out? Did I put the sensor too far down on my upper arm? Is the reader or the sensor faulty?

Any advice is greatly appreciated! Thank you.
