So today I had some sort of back spasm/ cramp thingy while I was cleaning my backyard on my left side and for like the next three hours after my left arm would shake when I picked up anything as heavy as a glass of water. But my arm stopped shaking (I haven’t wanted to try picking up anything heavier) but my back is still sore. I got nexplanon in my left arm so maybe that caused the shaking? I really don’t think that’s it and it’s just me overthinking 😂 but I wanted to know if I should get it checked out or wait it out some?
