There and Gone

This maybe a really obvious thing but long and short I've had a pinched nerve for just under a month. One Dr said I had arthritis in my neck, another said my bones are fine, and a third gave me steroids. The steroids pack was finished 3 days ago and up until yesterday I was still in significant pain. (Pain going down my right arm, elbows and wrists)

I had a long work day I powered though but last night I just crashed. imagine my surprise when I woke up this morning and there's no back pain. I've had some level of pain that has been distracting to impossible for weeks and now while I have some pain in my arm still the original focal point seems to be ... Done? Is it normal for a focal point to just stop?
