What is the reason why the bone marrow cannot be extracted

Bone marrow extraction will not affect the body! Generally, 1mL is extracted for bone marrow smear.

The locations of bone marrow extraction are generally: 1. Ilium (anterior superior iliac spine or posterior superior iliac spine) 2. Sternum 3. Other parts. Generally, the first two are common. According to your description, you have extracted the posterior superior iliac spine. You may feel sore and swollen in the days after the bone marrow extraction, but it will not exceed 3 days.

The cause of your low back pain may be due to lesions in the following areas:

1. Kidney, if cyst

2. The spine, such as a herniated disc compresses a nerve,

3. Other nodular masses compress the spinal nerves

It is recommended to take a B-ultrasound to rule out kidney disease, and then consider taking CT or MRI.
