Shingles (herpes zoster) is an acute infection of the nerves that supply sensation to the skin, generally at one or several spinal levels and on one side of the body (right or left). Patients with shingles usually have had chickenpox earlier in life. The herpes virus that causes chickenpox is believed to exist in a dormant state within the spinal nerve roots long after the chickenpox resolves. In people with shingles, this virus reactivates to cause infection along the sensory nerve, leading to nerve pain and usually an outbreak of shingles (tiny blisters on the same side of the body and at the same nerve level). The back pain in patients with shingles of the lumbar area can precede the skin rash by days. Successive crops of tiny blisters can appear for several days and clear with crusty inflammation in one to two weeks. Patients occasionally are left with a more chronic nerve pain (postherpetic neuralgia). Treatment can involve symptomatic relief with lotions, such as calamine, or medications, such as acyclovir (Zovirax), for the infection and pregabalin (Lyrica) or lidocaine (Lidoderm) patches for the pain.
Compressive pain is a result of pressure or irritation on the spinal cord, nerves that leave the spine. For example, if an intervertebral disc herniates (usually called a ruptured disc) and pushes into the spinal canal, it can cause problems with the nerve. Usually this pressure or irritation causes pain, numbness, and muscle weakness where the nerve travels.
Bridge: Still lying on your back with your feet flat on floor, lift your hips and torso off the floor into a bridge. Then interlace your hands underneath your hips and press your shoulders and upper arms into the floor, lifting your hips higher. Hold for 10 seconds. Lower yourself slowly back down, rolling down from the top of your spine to your tailbone. Repeat three times.
Poor Sitting Posture: The correct position of your low back should have a slight forward curve called a lordosis. When you sit slouched, this lordosis straightens out-or even worse-reverses itself. This loss of the forward curve in your spine can cause increased pressure on the small shock absorbing discs in your back. This increased pressure can displace your discs and lead to low back pain. Your physical therapist can teach you the proper way to sit to decrease, eliminate, or prevent your back pain.
How to do it: Loop a resistance band around your ankles and lie on your right side, supporting your upper body with your right hand and forearm. Extend both legs out, feet flexed. Brace your abs in tight and lift your top leg up to hip height, rotating your leg to turn your toes down to the floor, keeping tension on the band. Lift your leg slightly higher than hip height, pushing against band, with heel rotated up to the ceiling. Return to hip height. Repeat 20 times quickly and then switch sides.
