Had a look at symptoms of 'Mortons Neuroma' and feel this is not it...but..'Mortons Toe' sounds the likely cause, to make matters worse my second toe is a hammer toe!!!.
It is not painful this morning so I will wait and see how it feels after my run tonight. Perhaps it will only start to hurt after the long runs........I'm doing the FLM and I'm not going to let this stop me.
thanks again
