Hi ! The intense pain on her legs may or may not be related to ITP. If we corelate with the ITP, then she may be having this pain in case she has been given steroids
to control the ITP which causes osteoporosis
of bones. Also, a hematoma
in the spinal canal
with pressure on the nerves to her legs resulting in such pain may be excluded by an MRI after discussing with your family physician or the treating doctor. Till that your family physician may give her some anti inflammatory drug with a proton pump
inhibitor drug. Wishing her an early recovery.
