It might be your sciatica... I started having a similar feeling last week, a sharp tingling pain that shoots from my lower back all the way to my right foot. It's awful... Can't walk, can't sit or stand for long... Ughhhh.... I saw my physiotherapist today, and hoping to feel better after tonight's rest. I hope you do get better soon too!
Thank you so much I hope you get better soon as well I'm 35 weeks and I hope I don't have 5 more weeks of this lol I have an appointment tomorrow so we'll see how it goes lol
