In my experience so far, the predominant source of pain post-injury has been muscle tightness and spasms. Because my injury resulted in damage to upper motor neurons, which relay motor signals from the brain to the spinal cord, signals which relax muscles don’t go through. This results in spasms and over-contraction of muscles. Through my stay at neuro ICU, I was just starting to feel the intensity and frequency of muscle tightness and spasms gradually increase. I also began to discern differences between types of spasms and ways to manage it.
Some spasms, usually in my feet or legs, seem to occur when touched or moved. Others happen randomly and though not painful, are problematic when trying to sleep. At Harborview my usual solution would be to request oxycodone and Tylenol. Baclofen and Dantrolene, prescription muscle relaxants I take regularly, also provide relief though not as immediately effective. Eventually I learned to counteract random spasms by triggering spasms intentionally.
I discovered this by accident, while attempting to move parts of my body I was still able to move. For example, by flexing muscles in my neck and shoulders in a certain pattern and intensity, other muscles in my chest, abdomen, back and legs would be triggered, tightening similarly to a ratchet or boa constrictor. At first the sensation alarmed me and I would quickly request oxy, not sure if the muscles would keep tightening until I was unable to breathe.
After some experimenting, I realized I wasn’t at risk for suffocation for now, though it’s possible that could change in the future since I’ve learned from talking to others with quadriplegia that some do have restricted breathing from such spasms. For now it remains slightly uncomfortable but effectively reduces the occurrence of random spasms for varying lengths of time afterwards.
Weeks later when I was transferred to the rehab unit, I discovered I had the ability to intentionally start and stop a less intense spasm at will. By using slight emergent movement in my left leg in just the right position I was able to trigger repetitive foot tapping for up to 15 or 20 minutes. It may not have had much practical function but I theorized even limited movement might have some positive effect, whether improved circulation and flexibility, strengthened muscles, perhaps even enabling more emergent movement in the future. At the very least it provides a welcome sense of control over my body and also seemed to help prevent random spasms.
Muscle tightness is another ongoing issue I began to feel worsening while at neuro ICU. It could be temporarily alleviated with the same meds used for spasms as well as with massage, stretching exercises, electro stimulation and acupuncture. Unfortunately nothing I’ve tried so far has been able to prevent the muscle tightness from continuing to get worse over time.
Over the course of just a couple of weeks I began to feel more intensely how the muscle tightness began to affect my perception of phantom limbs. For example, muscle tightening in my legs caused my phantom limb legs to feel bent with knees up while my legs were actually straight and flat. Muscle tightening in my forearms made my phantom limb arms feel tightly shackled. Muscle tightening in my hands made phantom hands feel as if they were permanently holding rocks.
One of the reasons for the strengthening muscle tightness and spasms was the decreasing inflammation from the injury. My muscles at the time were still fairly strong compared to the baseline tone they retain without additional exercise. Unfortunately as certain muscles regain strength with the help of stretches and assisted exercises, tightened muscles and spasms increase in strength and frequency as well. Like many aspects of life after spinal cord injury, it’s a blessing and a curse.
