I have chronic achilles tendonitis and have been instructed not to run for at least 6 MONTHS by my physio, who I see weekly, after being referred by my GP as i was in so much pain.I am slowly getting better but this is because i actually taking her advice and not even attempting to run.
I can swim, cycle, do weights but that is it - i can't even use a cross trainer without pain.
I would rather do as she tells me than start back running to be struck down with this again - the pain was unbelievable and i was told it would have been better if i had ruptured my achilles as it would have healed so much quicker.
