I am young (26), physically fit, with no health concerns to note. For the last 3 days, however, I have had a tingling sensation in my foot that will not go away. Once during these 3 days I also was carrying my daughter and it felt like I didn't have the strength carry her a short distance as my legs felt like they would give out. This is really scaring me and I can't find much online. It's a long holiday so I can't get checked out just yet but I'm not sure if this is something I can wait to seek treatment on (a few days) or if I should go to the ER (I really don't have the money for an ER trip!) I can't think of any trauma / injury / or new activities that could cause this. If you have any ideas please let me know!
