The 'Coronation Street' actress headed for A&E after pounding the pavement on one of her latest training sessions, but following a scan and several tests medics are as yet unsure what is wrong with the 42-year-old star.
She said: "A few weeks ago I had a bad pain in my right side.
"I was in agony so I ended up going to A&E at Salford Royal, who were brilliant.
"I had a scan and they did some blood tests. I was sent home and told to see my doctor if it continued, and it did come back but not as badly.
"They haven't found anything and told me it could be hormonal or muscular - it's in my groin so it could be the training. I feel fine, so we'll see what the tests say."
Kym - whose baby Archie died just moments after he was born in 2009 - is running the half marathon for Tommy's, a baby charity who raise money to fund research into the causes and prevention of miscarriage, premature birth and stillbirth.
As well as physically training hard for the event, the former 'Hollyoaks: In the City' actress has been eating healthily.
She wrote in her OK! magazine column: "It's easy to indulge over summer but since coming back from holiday I've been eating healthily.
"Today I had a protein shake with banana and berries for breakfast, salad for lunch and fish for dinner.
"I'm drinking less - well, apart from special occasions!"
