Unfortunately I have been having a problem that started with some pain in the lower back (somewhat to the right of center), that began to radiate down the side and front of my right leg (all the way to the ankle).
Long story short, I have a small disc herniation at L4/L5. Since physical therapy did very little (there is one "stretch" which helps very much), I opted for an epidural injection of corticosteroids. This has done the trick thus far.
While the Doc did say that I may be able to get back to rowing/erging eventually, I decided that it is not worth the risk and sold the erg on Ebay.
I will now bike and walk for aerobic/cardiovascular exercise.
Thank you all for making this forum both educational and enjoyable.
Best regards
