<s>[INST] I had a double lumbar spinal fusion done in Feb 2011, I would like to know what long term restricitons I may have for a health lumbar. I am currently 39 years old, and try to stay active. I do core strengthening exercises wtih a stability ball 4 days a week. [/INST] Hello,I read carefully your query and understand your concern. Some precautions after the lumbar fusion are:Avoid strenuous activities, such as bicycle riding, jogging, weight lifting, or aerobic exercise, until your doctor says it is okay. Do not drive for 2 to 4 weeks after your surgery or until your doctor says it is okay. Avoid riding in a car for more than 30 minutes at a time for 2 to 4 weeks after surgery.Hope my answer was helpful.If you have further queries feel free to contact me again.Kind regards!
