Hi @tillysam, I don't think I ever experienced a heaviness feeling in the upper chest, neck and shoulder area during one of my 2 PMR occurrences other than the normal pains and aches that go with PMR. If I'm not mistaken, I think @sidsell1 and @cd54016 have posted about a heaviness in the chest area but I'm not sure it's the same as what you are experiencing.

I know from reading that people associate the heaviness with heart problems but it can have multiple causes including anxiety among other things. This article might explain it better --- What causes a heavy feeling in the chest?: https://www.medicalnewstoday.com/articles/324537

Did these new symptoms start after you switched from prednisone to hydrocortisone? Do you think it might be a side effect?
