Having had this problem for over 10 years I am willing to try anything - so will going down to Boots this weekend and try it out on a few runs within striking distance of home/pit stops just in case........
And as for riding a bike - did 4 hours on Sunday and when I got off the bike my right foot felt dreadful, as if the sock was really bunched up underneath - but it wasn't - all part of symptoms for Morton's neuroma - need to get this sorted - too many races to do over the next few months to have an injury!
Ran last night, in comfort whilst doing efforts then the pain/ache came back on the recovery home, took a couple of Ibuprofen and this morning no discomfort - doing 13 miles off road tomorrow, will be interesting as it is a few weeks since I have worn my off road trainers.
CB - tight boots, I agree that this could aggravate rather than help because I have found more problems with tighter fitting boots - be they walking or fashion (well sort of) boots.
Glad to find this post as I seem to have developed similar symptoms, which comes and go, went for a long walk on Monday wearing walking boots, I was very glad to get back to the car and take my boots off, iced my foot during the evening, it was still had on Tuesday so did not run, better now. But I know it will come back, it does sometimes wear off during a run. I think I will seek advice via a Podiatrist - often when it is uncomfortable the thought of something soft under the ball of the foot seems a good idea.
GP felt that as I was only just classed as osteoporotic in the spine the Calcichew would be sufficient. I have upped my calcium intake, have Ready Brek, eat sardines, take more milk and yoghurt etc etc.
I was advised to put weight on (5' tall 7stone) to go up to 7½stone and to reduce running - but from what I am reading the jury seems to be out on how much running is good/bad for you - I am happy to stick to no longer than ½ marathon distance so will do this and do some strength work in the gym, although I hate the gym, can't bear exercising indoors, although I will walk to the gym as it is close enough to do this.
So it does sound as if bone density can increase - so may be there is hope, at 5' I don't really want to lose any height!
