is ll so easy that you can continue lengthening up to 7cm?

Edit Post

as someone who is planning to ll, i am too scared. i think i will stop at 4cm from fear. but how do some people do 7cm? how do some people do two segments? that is hard to imagine.

if you are at 3cm and you get a sharp pain you have never felt before in your life at 3am in the morning and it stays until 6am, do you give up on lengthening or do you continue? what if you can not reach you r doctor until one more week?

i am not complaining about pain. PAIN MAYBE TOLERABLE. but what it means to the body is scary. is there a clear line between bad pain and normal pain? because many patients seem to experience all sorts of pain. muscle stiffness, numbness, tingling pain, shooting pain etc many people have said pain was 10/10 for them.

if people can get 10/10 pain how then are we to know if a pain is deadly and disabling or normal?

i can deal with lots of normal pain but if it means permanent damage to body then no.
