A few days ago, I got a sharp stabbing and very severe pain in my left foot (under my inside ankle and toward the sole), and it lasted about 10-15 seconds. Then exactly this kind of pain has repeated randomly since then, sometimes every couple of minutes, sometimes with several hours between them and in exactly the same spot. It does'nt feel like muscle cramping or something. It's just pure stabbing pain without any reason. It doesn't matter wether I'm sitting, walking o lying. It just keeps on attacking randomly. Can anyone help me please?
