You aren’t giving yourself enough time, you just had the surgery! It takes months to heal. Your body has been through a trauma. Muscles, nerves, bones have all been manipulated.
I thought my laminectomy was painful, but nothing I didn’t expect. And it was nothing compared to the spinal fusion I had a year later. Yikes, that took over a year to recover from.
Is this your first surgery ever? I’ve had many surgeries over the years. Maybe you just didn’t realize how it impacts your body.
