You know that sounds just like what I had. I never noticed it particularly, unless my husband touched the spot.
I am not sure where it came from and why I had the tenderness and sometimes pain. No one could find out what it was.
Then my husband started talking me into changing my supplementation and he also got me some pain relief oil.
I have meen sore and pain free for over a year and I love it. Also my lower back problems, as well as my sciaitica pain has improved alomost 80%.
Hope you'll find something for your pain.
If you are interested, leave me a message here and i'll let you know what I am taking.
Good health
