Hello Doctor. I Am A 20 Year Old Male, Daily

Hello Doctor. I am a 20 year old male, daily marijuana smoker for about a year now, my diet has been horrible for the past 2months; I used to be in great shape but felt lower back pain that would sometime shoot down my leg. Doctors have diagnosed me with scoliosis, i will be seeing a chiropractor soon. My question is I woke up 2 days ago and yesterday my hand was very week I could squeeze my fist eventually it went away but I feel abit of tingling feeling in my thumb and shoulder blade( both on the right side) could this be due to my scoliosis or poor diet/lifestyle. Also I haven't been drinking much water.
