I suffer from radiation damage due to throat cancer 10 years ago which causes neck spasms at least 5 times a day especially if I look to the left. I have tried every medication and creams including steroid injections to the base of my skull. Then one day my wife found a jar of some old cream in the back of cabinet called ONE EIGHTY muscle cream . I applied to my neck, shoulders and jaw and my spasms disappeared never to happen again. I have suffered for 8 years of these spasms that when they happen it looks liked am going into a apoplectic fit at last for about 15 seconds. Heard you all to try this cream look it up they make other types of creams as well. Not sold on Amazon. I hope people try it cuz it’s surely a lifesaver for me where no doctor could help.
