I took nurofen 2-3 times per day for about 2 weeks and purchased a pair of asics (I think) trainers that are designed to support the arch and heel of sufferers properly.
I found a 95% improvement just in these two things.
Spend the $ on shoes/inner soles.
It's so well worth it.
I had suffered for approximately 8 months and it had become really debilitating.
I only have flare ups now if I wear the wrong shoes and am on my feet all day. I take nurofen straight away and that seems to relieve a lot of the inflammation.
