I know exactly how you feelbecause I had knee surgery and was laid up for months. I took the pain not the pills. There are other things to help manage the healing.I cannot say for sure. but I would wait until I was healed before such a drastic step. I know it is just hair, but that hair can give you strength and pride.Pain pills can make you more depressed. Music, walking(Iknow painful) writing a journel , friends, even on line, will all help you heal. After you are better and the fog of pain meds are gone, then decide to let the dreads go. You might comb them out, or you might just end up keeping them.Sending you love and healing and remember you are not alone.
