The most important thing at this stage is to get a diagnosis from an experienced running physio to establish the risks of completing your marathon. You may be pleasantly reassured by what they have to say and what can be done even at this late stage so please get in touch with Lucy and her team now.
They will advise you on what hands-on treatment, taping, massage, foam-rolling and exercises are useful for you to do, even if it is literally a few days or hours before kick-off but the sooner you get in touch the better.
They will also put you in touch with a Sports Doctor or Pain Consultant to discuss if any medications or injections could help get you safely to the finish line.
