How did you guys get thru this ???

I’m able to bend 120 but the last 15 are killing me… it’s soo painful… I don’t know if I have less pain resistance or it’s just really that painful. Is there a easy to do this ??? Btw I’m 6 weeks post op ( Acl reconstruction + lcl augmentation + middle meniscus repair, hamstring graft ) . Pls advise.
