Needs workup and clinical correlation in detail
Thank you for asking
Pain hyoogastrium with no uterus
non complain of urinary troubles association with walking and intra abdominal pressure ( coughing) and postures need a little more detailed history and physical examination and some work up to assess and categorise. Bowel movements and habits are important here.musculoskeletal pains need to be ruled out too. Bladder infections should have urinary complains so least likely.get some Antispasmodics and see if they help.seek a gastroenterologist
and let them run some labs and see if they come up with the diagnosis.
It's too early to comment on.20 years old history of hysterectomy
is not significant here except that the adhesions resulted might have some role in the pain here.
Needs work up and a complete clinical corrlation for further management. Seek help.
I hope it helps. Take good care of yourself and don't forget to close the discussion please.
May the odds be ever in your favour.
