Hey all.
These are the best practice guidelines
https://cks.nice.org.uk/topics/plantar-fasciitis/management/management/ which were developed from looking at all the current research of what has been shown to work (or not). Sometimes research hasn't been done into certain things, but as
@pete evans implies above, there are lots of weird and wonderful things out there, that might just be taking your mind off whilst nature takes its wonderful course...
Generally the above advice will work, but if symptoms continue, then it really is worth escalating, as there are other conditions which might need a different approach and a different team to deal with them, that isn't necessarily ortho or physio or musculoskeletal.
Having dealt with this for many people (and me) on arduous courses and activities over the years, I've found it is mostly brought on by a change in something - a sudden increase in activity, taking on something new, a change in footwear to something with less arch support / heavier / needing more foot and ankle muscle work to stabilise (so they fatigue quicker), suddenly not wearing shoes (beach holiday?), having to put "posh shoes" on for a meeting / job interview / wedding, a lay-off and then return to normal activity, age-related reduction in muscle strength around the foot and ankle etc. etc. Sometimes even small things can be enough of a change to trigger it!
For those of us who spend a lot of time in wellies, there is no problem with putting insoles in them to provide some extra support (I use a set of X-line TPDs in mine (I don't get any commission) which are comfy and at about £30 online, cheap and long-lasting) if it helps for you.
As a quick fix for if you just have to crack on, making a leukotape "fake" plantar fascia can be really helpful (bit like a sling if you hurt your arm, or a brace if you hurt your ankle). Number four on the link below is just about how I would normally do it - just be aware of all the warnings about tape allergy and not tourniqueting your foot!
If in doubt don't be tight (you know who you are - happy to spend hundreds on a new bit of kit but resent spending to see anyone about the most important bit of kit - You!) and book in to see a Sports and Exercise Medicine specialist clinician for a proper diagnosis, prognosis and treatment.
There are a variety of ways to tape your foot. We have chosen to introduce 4 different ways. Depending on the stage/severity of the pain, body characteristics, and the sports you are participating in, you can modify the taping method. The idea is to use the least amount of tape to provide the...
