While I rate the product extremely high (5/5 stars) and comes with my highest recommendations, I also wanted to highlight some of the dangers of using this tool as I accidentally victimized myself…This cane a treasure, and you truly don’t understand the power behind your own force. For reference, I am 30 year old female veteran and I suffer from killer neck, shoulder and upper back pain from carrying around a rucksack that weighed over a 3rd of my own body weight (125lbs).While using the product, I have experience incomparable pain relief. Unfortunately however, I have never had a professional massage, nor did I know anything about a “deep tissue massage,” which is what I ended up doing one day… I applied DEEP pressure to the trigger points in my neck and trap muscles and within 10 hours, I was in excruciating pain all over my body. I had successfully poisoned my blood with metabolic toxins that were released during my seemingly innocent massage. I woke up at 3:33AM with a splitting headache, nausea, and my body felt like it had been blown over by a semi truck. Every movement and gentle touch to me skin hurt me. The discomfort lasted for an entire 24 hours and how I was able to remedy the poisoning was as followed:*** Number 1, please be hydrated before AND after using this cane. Hydration is key is making sure the proper nutrients can make it where they're supposed to be. I am a great example of someone who does not drink enough water and I definitely felt the repercussions.• I drank three 8 ounce cups of warm water with a good shake of ground ginger, ground turmeric, and ground fennel added. I topped it off with a teaspoon of lemon juice and a teaspoon of honey (adjust any measurements to your pallet and exclude anything you may be allergic to). I consider this to be my “antibiotic concoction” and it helped to break down a lot of gunk and move it on filter-organs.• I took a hot, steaming bath that evening to promote blood flow and healing. I found that any time I applied heat the pain would completely subside whereas ice I felt made my blood vessels constricts, therefor restricting blood flow and making me feel even worse.• I fed myself healthy proteins to replenish my temple. That included a whole avocado, 2 bananas, and a sweet potato throughout the day for fuel. I felt so awful that food sounded horrible but the three things above were entirely manageable during the nausea stages (but I knew I needed to eat or I would continue declining).I woke up the following morning around 6AM and my body had clearly done one heck of a job pushing the toxins out because WOW did I sweat, and woah did it smell sour (sorry for the visual). The reason for this is because the lactic acid was released thru my pores and held a particularly unforgettable scent of ammonia. I also felt 100 better. While my muscles were sore from the massage, my body felt clean and clear and under control. It’s safe to say I have learned my lesson and I will from now on only apply very minimal pressure, and will leave the deep tissue massage to professionals who know what they are doing, and how to look for warning signs that a client may be experiencing a negative reaction from a massage.All in all, I DO recommend this product as long as you are aware of the risk when using it. I think it would be highly beneficial for this company to include a card they can slip into the box that will give a brief description not only on how to use it, but how to prevent injury such as the one I experienced above. Injuries like this CAN cause serious medical emergencies for example: If you press on your neck with too much pressure, there is a chance that you could accidentally sever your artery which could lead to a stroke and/or death. You could also cause yourself to have a stroke, no arterial severing necessary.Take care and happy healing, all!I hope my experience helps to make yours better.
