I can speak from unfortunate but significant experience here. In December 2005 I remember the day I crushed my L5 disc, it was a Heel side on a Madd 170 at Mt Snow north face. Thought I had "pulled" a muscle as all the way home I was uncomfortable. January 30th at about 11pm the disc blew and I was scheduled to leave the following Saturday for Colorado. Ended up in the hospital at 6am due to the non stop pain. Woke up a 12 and left the hospital. Freaking about the $4000 I was about to lose on that trip I used my connects to get me in for an MRI and Ortho visit that Wednesday. He asked me to do a few moves and said you can go on your trip, will get you an injection but just take it easy. At that point the top of my right foot was burning. The shot totally numbed my foot and my back didnt hurt the entire trip. Once I got on the plane home my foot started to burn again. I got another shot in March but doing PT they noticed I had foot drop and it was not progressing. I sought out a surgeon and he was like Your foot is numb and you have foot drop, why did you wait do long, you need to be operated on ASAP. Literally 1 hour after the procedure I had more strength on my foot and it was clear he had decompressed the nerve, little did I know the damage to the nerve was done and irreversible. Now my right calf is about 20% smaller than my other leg due to muscle atrophy, I have some slight foot drop but Im able to function really well.
Where does this long winded story go? I have atrophy in that leg and the hamstring is part of the problem now. I do good for months without my back chirping at me but when it starts my hamstring is tighter than normal. Siting in my job contributes and over all lack of a good fitness regiment this past 6 months I believe is the culprit. When Im going to the gym consistently my back feels the best. I spend the first 30 minutes at least on the mat stretching and using the foam roller. Its troublesome because I know I will never regain the full strength in that leg due to the nerve damage. I can only hope to keep what I have left. At soon to be 57 I wonder how I will be walking in 10 years but Im still going to try to ride as long as I can.
Keeping your hips mobile and hamstrings loose are the best things you can do. If you feel like you have nerve involvement or compression dont wait 4 months like I did
