Hi. Does the pain ever seem to radiate from your back around to the navel area?
Sorry - it was impossible to respond from my mobile - a pop up from a 'Family Physician' kept coming in and then I was asked to pay for another doctor as you weren't around - even though I have a subscription.
The pain wasn't really in my navel area but seems to be now that you've put it in my mind (see what I mean about somatising!) It's mostly where I first mentioned but I also have some back pains which my osteo says are muscular and do feel like they are when I dig my thumb in and massage them.
I can also press various parts of my stomach and feel pain.
I do pilates for my back but wonder if I may have strained something. Or picking up grandkids (my own not random ones)
I'm not too worried except that having had two cancers (testicular and prostate) I tend to go there whenever I have anything.
I also work a lot at a desk as I'm a writer so my posture not great -and I have a slight scoliosis and also wear and tear at the base of my spine (spondylitis?)
