Not a v nice subject sorry! Woken up this morning feeling like I need to go to the toilet but whenever I try I get really bad shooting pains in my left hand side. Pain is there a bit when I'm not going to the toilet but not as bad, just feels uncomfortable. Since I got the first pain my left leg has had non stop pins and needles and has gone a bit weak. What's the best thing I can take to help get rid of both?
