Seems related: burning in second small toe and high blood pressure 170/111. what is that? what is a severe hbp reading?

See MD NOW!!!: I don't think the burning on your toe is related to your very high blood pressure, but your BP is high, and you need to be seen right away. If you smell smoke from your toe, run to the doctor! seriously, untreated high BP leads to kidney failure and heart disease over the long term, and stroke & heart attack over the short (very short) term. Go get checked!
