Yes, mine is intermittent, it is not there all the time. If I overdo it, it hurt. If I lift my grand daughter (18 mths) I have to put her down as it feels as though I am having a heart attack. If I twist a certain way etc. Havent had itfor a while because I now watch what I do all the time. Very frustrating.
It got worse after being on steroids for a year as my weight had gone up.
Hope you feel better soon, and get things sorted to put your mind at rest.
