You have had a BIG surgery and your body has been through major trauma. Fusion is really a big carpentry project that subjects the spine to a great deal of force. I'm not sure what your expectations are, but I think you are doing very well for being two weeks out from such a big surgery.

You will find that recovery is a long, slow process, sometimes involving a couple steps forward followed by a step back. Do not be surprised by this. It is very normal!

I would suggest that you try several short walks each day. It is important to get the blood flowing and to keep the spinal nerves stretched out. This is also useful in the prevention of scar tissue forming around the nerves. So, even if your legs hurt, be sure you walk several times each day. Distance isn't that important. You can ice when you get back, or, in your case, you may find a heating pad more comforting.

When you are lying in bed, you can do "ankle pumps" to keep the blood circulating. Just point and flex your foot from the ankle, and alternate feet. You can also make ankle circles while lying in bed. This will keep the blood circulating and keep blood clots from forming.

For now, limit the amount of time you spend sitting. It is better to lie down when you are not walking. Sitting puts 30% more pressure on the lumbar spine than standing so while you are healing and trying to fuse, limit your sitting.

Sounds to me like you are doing very well. Follow your doctor's instructions, take your meds on schedule, and, keep walking!!

Any time you have symptoms that are abnormal, dont be afraid to call your Dr. They are the ones that need to know what is going on. Especially so soon after surgery,
