Hey guys! A little background on this..

I was having issues with my legs and I went to my doctors and he told me I needed to get Physio done, I’ve had three sessions of physio now. He’s also put me on medication called pms-Meloxicam, he didn’t explain too much what it does or side effects etc, i’ve been noticing this happening to my legs usually at night before bed, I thought maybe the meds were doing it? i’ve taken them continuously since i’ve gotten them I think maybe Jan 20 or 21 but I noticed them like this before I took my medication tonight, my next appointment is march.. should I call him now?
