Soma vs Flexeril – Which Is Better For Neck Pain?     

According to studies, in people with acute back pain or neck pain, cyclobenzaprine (Flexeril) is consistently more effective than placebo for treating muscle spasms, relieving pain (including neck pain), and increasing function. Furthermore, there is some evidence that this medication is possibly superior to similar drugs for treating individuals with musculoskeletal conditions.

On the other hand, carisoprodol (Soma) should be phased out as a muscle relaxant in favor of much better and safer options. However, if it’s prescribed, this drug should only be used for short periods of time due to the lack of evidence for effectiveness when used longer.

In conclusion, cyclobenzaprine is more efficient in reducing neck pain. Nevertheless, both medications have plenty of side effects.

6 Home Remedies For Neck Pain

#1 Good Healthy Sleeping Positions & Patterns

If your neck is bothering you, you should pay attention to your sleep positions since when you sleep on your stomach, you may end up twisting your head one way or the other for hours at a time. Therefore, sleep only on your back or on your side – never on your stomach. In addition, aim for 7 to 8 hours of uninterrupted sleep every night (including weekends).

#2 Stay Hydrated

Maintaining good hydration habits may help to prevent cervical disc (comprised of 6 cervical discs which rest between the cervical vertebrae) degeneration, which is a leading contributor to neck pain.

#3 Acupuncture

This natural treatment method is based on the science that there are more than 2,000 points on the body which connect with 20 meridians. These meridians conduct energy throughout the human body.

According to research, acupuncture can be more effective at treating chronic neck pain than many allopathic remedies, plus, it has notable fewer side effects.

#4 Epsom Salt Bath

The magnesium sulfate in Epsom salt acts as a natural muscle relaxant which helps reduce pain and swelling.

#5 Reduce Your Stress Levels

Pay attention to what stresses you and sort it out to get rid of neck pain. The best methods to reduce stress include – mindfulness meditation, Tai Chi, and yoga.

#6 Turmeric

This spice is native to South East Asia and southeast India. Curcumin, the main active compound in turmeric, has potent antioxidant and anti-inflammatory properties. Also, combining turmeric with black pepper increases curcumin bioavailability by 2000 percent.
