I was rear ended in a car accident when I was 24. Since then I have been dealing with sharp stabbing burning pains in my neck. After 2 years of pain management my doctor has exhausted all techniques. Until one day he put his finger in the dip in my shoulder. INCREDIBLE PAIN surged, I felt like I lost the ability to stand or sit upright. After finding this out there isn't much that is able to be done about the horrible sensations that start in my shoulder and shoot to my neck. No prescribed external topical applications have been successful.
One day I was in so much pain I just started throwing different creams on myself. Surprisingly, I found that hydrocortisone cream temporarily relieves these neck spasms long enough to "forget" about it and move on to something else. I would say it's an aid to help me relax.
At first I had to apply frequently because I was so stressed from the pain itself. But used less eventually. Keep in mind that a hot shower stream of water beating on my neck caused "white light" ten out of ten pain that took me to the ER because I freaked out.
So I suggest applying this to a very sensitive painful area of the body due to deep debilitating muscle spasms. It really helped me get past the pain long enough to distract myself with normal activities.
