I remember that feeling. The only thing more difficult than climbing down that hill to Moliniseca on a hot day, was cancelling my Camino for this year. I hope everyone who wants to walk in Spain can do it safely next year. I can't wait to wish everyone I see a Buen Camino again.
there is a nice hotel below this hill accommodations for Albergue and private rooms. Meals and breakfast provided at reasonable price excellent place to relax, there is also a pool and the view from here is exceptional.
The first time I walked down completely off the road and on the trail I almost lost consciousness at the bottom. My friends revived me, and carried my pack into town for me. It was awful but it obviously wasn't bad as what you encountered.
Because of all the rocks, I'm not sure that they can do very much to improve that part of the Camino. Fortunately the traffic on the road is normally very light and has not been a problem. Of course I stay alert and assume that the driver is not expecting to see a pedestrian on the road but having said that it still feels safer for me.
