I just found out my hip pain was caused by low ferritin even with normal hemoglobin and hematocrit and no blood donation. So, check your ferritin level!
Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Low levels of ferritin lead to iron deficiency anemia, which means you have too few red blood cells. High levels of ferritin can damage your joints, heart, liver, and pancreas.
Last month I checked my ferritin with an Iron panel, it was virtually the same as in 2018. So no problem there.
I checked because I felt unusually fatigued, but now I think it might have been I had covid back in March. Now i feel pretty much back to normal.

But thanks, I didn't know low ferritin could cause hip pain.
