Starting a week ago today I was at work and started having tingles down my legs and in my hips. I also have some cramping (even a toe cramp that night). Next day (my birthday- 20F) same thing again and I had lower back cramps. So for a week I’ve had weird body sensations. Tingles, ache arms, cramps in back and legs, lower back cramps. And now I’ve noticed weird muscle contractions? Like I’m lying in bed and I can feel a small muscle in my leg almost flex and let go?? It doesn’t hurt. I’m so worried idk what’s wrong with me. I can’t sleep right cause I can’t get comfortable with all these feelings. I know ur not dr but has anyone experienced this.
