I have numbness in both feet (to which I have seen the GP about and have been put on folic acid as I'm low on this and have been on these for 5 weeks) I am now getting tingling from my lower back to both my feet when I look down, along with this I have numbness/tingling in my left thumb, middle and ring finger and also tingling when I extend my left arm (tho I have no loss of strength). I was diagnosed with ocular myasthenia back in 2014 (I currently this is very mild and does not affect my day to day life)
