hi,
thank you providing a brief history of you. Since you mentioned you get this kind of pain + you had onco also + you do regular heavy lifting works.
to come to an assessing part of the
oncologist it is his job to figure out if anything is wrong. Chances of getting pain after the pressure might be symptomatic but not have damaged anything. still you are going an
ultrasound you will get some inputs as well.
let's understand that when u keep hand behind the hip you get pain or else in normal anatomical position you don't get any pain.
why don't you try doing some regular exercises under the guidance of a physical therapist who can help assess your weaker muscle groups and help you strengthen them.
you can even rule out any issue with the spine if any
nerve is getting trapped. for which an NCV or
MRI will be of great help.
you can even take the hel of a physical therapist who can use some therapeutic ltrasound and
TENS for reducing the pain symptoms.
improving the
metabolism of you body will help it to fight against infection too. With the exercises you will even have improved immune system which may rule out the nodal cancer issue which your onco is suspecting as your exercises indulgence will suppress all symptoms and make your onco wrong and make you happy alot.
with the grace of God I wish you a speedy recovery. never get demoralized by anyone. you should be a fighter and prove that you can make a change for your own self.
