Was your Grandad’s shoulder better after you took on his pain? Did your Grandad know about discharging energy after healing? Did you do this?
You could have had a mental block after that startling experience. I would suspect more that this caused you to have some previously unexperienced fear about healing & this fear is more than enough to keep you from accessing the frequency of energies needed to heal.
It isn’t the objective of the healer to take on the person’s illness or problems. It is important for healers to discharge any energy they take on from the patient. Some healers discuss using their self to channel the Universal energy, but keeping their own energies apart from the healing.
You might be able to do various things to address this. Actively discharge any energy that remained in your energy field from that incident, no matter how long ago it was. This link is about a different issue, but the same things apply about discharging any unwanted energies.

Visit w/ your spiritual team to tell them you want to clear your energies & resume to be a healer. Move into the view that you WILL get back to accessing this energy & away from looking at this as a permanent thing. See it as more of a mere interruption. Work on moving past the fear that this incident caused. This fear will likely be part of the energetic refuse that is mentioned in the above link. Instead of healing others, focus right now on doing the things that will raise your expand your consciousness.
It may be that something like appreciating this incident gave you a first hand experience that one can actually take on another’s energy will help you move past it. Loving it for the learning experience it was.
