@marinelastef I have had occipital nerve blocks and many nerve blocks in other areas. I am curious how it was determined that the blocks were the cause for the muscle and nerve damage and weakness. I ask this because I have some doctors that cannot explain some very rare but serious health issues that no institution has ever been able to pin-point the cause and your question peaked immediate interest to me. I have cerebellum volume loss, multiple-system atrophy including the esophagus, vocal cords, legs, arms, stomach, bladder, polyneuritis and a host of other issues that were diagnosed after the occipital nerve blocks.
