Hi: I have had on and off lower back pain, more on one side - most often lower back just above the buttocks, for 5-10 years. I has typically been unbearable for 3-5 days, then went away for years. Now, since mid Jan it has not gone away. Had an MRI done, and Dr thinks it could be a pinched nerve, disk issue, and/or arthritis. I am 48 - I work out every day - no kidding! I use weights, but not to 'body build', but to create resistance. I typically work out at least 30 min per day. I was in an auto accident 30 years ago, resulting in TBI - but I am very lucky. My recovery was remarkable, and to look at me in 'daily life', you would be shocked to know this. I have dexterity and balance issues, and other than those, I live a very nice and comfortable life. When I called the ortho office for the appointment, the nurse asked me why I was calling, and I told her - as my primary Dr told me to say - that I have an 'Abnormal MRI of the lower back.' Her reply is what makes me uncomfortable. She said, "Oh my! That's not good!" I asked her to clarify, but I think she felt embarrassed and told me she did not mean to alarm me... Any reason I should not be worried??? Thank you!
