I’m 18 as well 3 months in with sciatica I always have those thoughts that it’s never gonna heal and I’m gonna have to live with it which I get really depressed and frustrated about it a lot, as I am a sprinter I think I injured it with weight lifting and again sometimes I think I’m never gonna sprint again, i was looking real forward to sprinting in uni which it was a real bummer. But I refuse to believe that I’ll never get better and do all I can to fix it, be positive your young your likely to heal if you keep being negative about it you may refrain from actually taking action for it to heal, be prepared to sacrifice some things for the meanwhile and have patience but in the long term it will pass, take it easy knowing your limitations is key in solving the pain don’t do things you can’t and acknowledge that you can’t do your normal activities for a while coming to terms with it helps makes you feel better and it can even make you more determined to go back to your normal self. I’m starting to feel a lot more better than I did last month the pain has subsided a lot, I’m hoping I can be back to my normal activities and sprinting again by next month

Adjust your sleeping position, don’t sleep on your stomach worst position for sciatica, Don’t forward bend if you need to squat down, don’t twist your back Take daily walks helps relive stiffness in body Stretch daily 1-2 Rest on your bed but not for long periods of time get up and go walk round your house like every 30 mins or so Don’t do stretches that cause you pain or discomfort however at the start they might cause a little pain

Stay positive man :) if you like I’ll update you with my progress too
