1. No. This is part of the normal aging process in the spine and it is not possible or necessary to treat these changes.
2. I would not recommend any surgical treatment
based on your MRI
alone. If you have only back pain
then anti-inflammatory medication, core strengthing and physiotherapy
may be of benefit.
3. This is unlikely to have occurred because of an injury
but as a part of the normal aging process in the spine. Yes I would continue at the gym.
4. Cost for the consultation - this is the free public forum and so there is no cost.
