I need to get this checked out. It's not like fierce cramps where muscles lock right up, it's my back-of-thigh muscles (and sometimes my calves too) that get really tight and uncomfortable in the evenings and at night, alongside of restless legs. I've tried everything I can do unmediated - exercise, magnesium, molasses (internally, not externally!) but it's getting a bit relentless. It got worse as soon as I went on hormones and then tabled out, but now it's worse again.
