Maybe some yoga asanas or chi gong practice could be helpful against the tensions?
I know these kinds of movement during meditation as a phase. It is coming for a beginner and it is going when the topic is finished.
Tensions in the body relate to mental issues also, in my experience. But one can resolve it also with physical exercises.

From beginningless time, are suffering,
What can we do with (just) our own happiness?
