She was taken to the Northumbria Specialist Care Emergency Hospital in Cramlington following the incident on Saturday evening.
A spokesperson for the North East Ambulance Service said: “We were called at 7.39pm on Saturday, April 25 to a patient injured near Royal Border Bridge in Berwick.
“We dispatched a double crewed ambulance, a clinical care manager and a specialist paramedic; also requesting supporting from Berwick Coastguard.
“A female patient was transported to Northumbria Specialist Emergency Care Hospital with multiple injuries.”
Berwick inshore lifeboat was launched at 8.28pm following a request for assistance.
The casualty had fallen 15 feet onto mud and rocks by the River Tweed. The tide was going out at the time.
Helmsman Robert Frost said: “Once on scene the paramedics were already there and had the casualty made comfortable and in a stretcher.
“The RNLI crew, with the help of Berwick Coastguard, carefully carried the casualty to the lifeboat and casualty was then transferred to the pontoon in Berwick harbour for ease of access due to tidal conditions.
“On arrival at the pontoon, Berwick and Eyemouth Coastguards both then helped transfer the casualty from the lifeboat to the ambulance along with ILB Crew, Richard Cox, Michael Percy and Amy Faragher.
“All RNLI volunteers who attended the call out followed the correct Covid-19 guidance and procedures as laid down by the RNLI and government advice.”
