Spinal cord injury is one of the most devastating injuries that can occur because if its potential to leave a person totally disabled.

Every year thousands of people injure themselves jumping into pools head first because they don’t realize the depth of the water is not sufficient to withstand a close impact. The projectile force that a head can be exposed to can literally crush the cervical spine, causing permanent damage to the spinal cord.

The cervical spine begins at the base of the skull and is made up of seven vertebrae and eight pairs of cervical nerves. It protects the spinal cord, supports the skull, and allows head movement. Serious injury to this area typically paralyzes a person, and often injures vital respiratory nerves.

Location often determines the severity of a spinal cord injury. For example, an injury at the neck or cervical spine level may result in paralysis in both the arms and legs, and the use of a respirator to breathe. An injury to the lower spine, may only affect the legs other parts of the body below the injury site.

Spinal cord injuries should always be taken seriously, and if you think someone has suffered one, it’s important you don’t try to move them – keep them still until medical professionals arrive.

Signs of a serious spinal cord injury might include:

• Fading in and out of consciousness
• Extreme back pain or pressure in the neck, head or back
• Weakness, loss of coordination or paralysis in any part of the body
• Numbness, tingling or loss of sensation in the hands, fingers, feet or toes
• Loss of bladder or bowel control
• Difficulty with balance and walking
• Impaired breathing after injury

From a medical perspective, repairing spinal injuries has had limited success. Many times, the damaged nerves cannot be repaired, and patients are left with diminished motor function and sensation. This is why significant research is being done in the field of regenerative medicine. The use of stem cells, right now, seems to be the most promising treatment for the future, but we’re still many years away from fully integrating spinal cord nerves.

This is why prevention is key. When you’re young, you think you’re invincible. But it doesn’t matter what physical activity you choose to do, you always have to acknowledge that your body has limitations. You have to be aware of your surroundings, and whenever possible, think of using protective gear.

Dear Yvonne,
Sometimes my girlfriend will laugh during sex, which weirds me out. Is it because I’m doing something wrong?

Dear Tad,
Sex is a fun activity (and if it isn’t a good time, at least most of the time, you seriously need to question the relationship and what you’re doing). Inuit Eskimos refer to sex as “laughing time.” So is it any wonder that lovers aren’t always serious in the sack?

Sex involves feeling good, expressing yourself, and sharing amazing, positive moments with somebody you care about. Laughing can be a great compliment because it indicates your lover is letting go of stress and getting into the moment. While many people worry that their lover is laughing at them, it is more likely that such an expression is due to tickle sensations, disbelief at what is being experienced or simply joy.
