how to treat scoliosis upper is 40 and lower (hips) is 50-degree?!

i hate to say it but most curves above 40 degrees require surgery. i think you will have to go for it or it is most likely that it will keep getting worse and you want to have the surgery sooner than later.
i had 55 degrees in my upper back i had surgery last year and now im totally fine :)
other options will not decrease the curve. a back brace may stop it from getting worse but you can't wear a back brace your whole life and they are relatively uncomfy and troublesome.
some people try excersises but these are rarely effective on larger curves like yours. there is no other permanent solution to stop or correct the curvature without surgery.
the operation includes metal rods to straighten the spine. it sounds really scary and weird but trust me you cant even feel them or anything afterwards!
it is a pretyt safe operation there is a 1% risk of paralysis but thats very rare...
the only advice i can give is do some research and find the best scoliosis specialists around because you need a good surgeron to do this operation. ask for their advice too
but if you want to chat to someone whose had it then you can message me :)
just try not to worry about it <3
