apologies for taking so long to respond. it is not the way we usually roll here.
since you have so much tension it could be putting pressure on some nerves, hence the pain.
However, the pain could have started, then your body is tense waiting for the next zap.
Best thing is to make a doc appointment and get a physical with blood work. Perhaps a CT scan
In the mean time try some warm heat on you shoulders.
