There are many painful operations, such as open surgery on the heel bone, spinal fusion, hysterectomy and proctocolectomy, as follows:

1. Open surgery on the heel bone

If a person has a fracture, surgery may be needed. Surgery is not always necessary if the bone has not moved too far. In order to repair the fracture, the surgeon must cut into the skin to break the fracture, and then fix the bones together with plates or screws. It is easy to damage the nerves around the heel during the operation. With the attachment of screws to the bone, it can make the operation and recovery painful.

2. Spinal fusion

The bones that make up the spine are called vertebrae. Scoliosis and degenerative disc disease are one of the medical problems that may affect vertebrae.

if the motion between vertebrae causes pain, the doctor may recommend spinal fusion surgery. This process connects two or more vertebrae to prevent them from moving with each other.

Sometimes surgery involves bone transplantation, in which bones are removed from the hip joint and put into the spine to help the vertebrae fuse together. Significant or even chronic pain may be caused after bone transplantation.

3. Hysterectomy

Although these muscle fibers are almost always harmless, they may be the cause of infertility.

If the myoma is large, open surgery may be needed. Open surgery is usually more painful and takes longer to recover than keyhole surgery. In myomectomy, the surgeon will cut into the myoma. They have removed the myoma, and they will sew up the incision with a needle.

4. Rectocolectomy

This operation removes the large intestine, rectum and anal canal, which constitute the lowest part of the intestine. Rectocolectomy can be used to treat ulcerative colitis, intestinal cancer and some forms of Crohn's disease. If this is not appropriate, the surgeon will use open surgery.

5. Complex spinal reconstruction

These include spinal stenosis and scoliosis. The high concentration of spinal nerves and nerve endings may make this operation very painful.

6, perianal abscess surgery

There are abundant nerve fibers around the anus. Perianal abscess is an abscess around the anus, and anal fistula is the rupture of the abscess, which forms a breach in the perianal skin and causes long-term pus.

The operation of perianal abscess needs to fully open the wound and scrape off the necrotic tissue. The operation of perianal abscess generally doesn't hurt much, because it is done under anesthesia. The main pain is dressing change after operation, removing the gauze inside, removing the necrotic tissue and filling it again.

Moreover, the healing time of anal fistula is very long. Although the abscess is removed, pus will still flow out, which is an important discharge. Change gauze and clean the wound every morning. It takes several months to completely heal, so perianal abscess is a long-term process.

7, hemorrhoids surgery

hemorrhoids surgery is also more painful after surgery, mainly when defecating after surgery. If the stool is dry and hard, the pain can be imagined when passing through the surgical incision, and after defecation, the anal sphincter contracts, which may induce lasting pain again. It is a long and lasting painful process.

8. Sex change surgery

Because this kind of surgery has a small audience, it is indeed recognized as the most painful surgery at present. Sex-change surgery is really painful. It's no joke. Sex-change surgery involves cutting off the penis, reconstructing the vagina and labia, filling the reconstructed vagina with gauze, and shaping it with a mold after surgery. You can imagine the pain of dressing change every time.

Therefore, transsexual surgery requires not only strong psychological endurance, but also very strong pain tolerance.
