Hi everyone, I would love to get some information. I'm 17 years old and was diagnosed with servere degenerative disc disease and spinal steneois. I do not know much about these conditions since i'm rather young and have not paid attention to these. My L5-S1 disc is completely gone. How did I get DDD and a disc being completely gone at such a young age??? My doctor said it may be due to genetics and lifestyle but are there other reasons? Also since my disc is gone will it most likely lead to me having surgery to replace the disc?? As of now i'm on meds, physical therapy, and steroid shots and will go back to my doctor in 3 months to discuss my pain level. I will be getting second opinions thou. Thank you.
