Is self-ruqyah recommended, or listening to it, when feeling distress, palpitations, heat, and fear upon reciting verses of punishment or sorcery, and are there any other recommendations?

If a Muslim is able to perform Ruqyah on themselves, that is preferable. This is done by reciting the Ruqyah with a present heart and understanding its meaning. There is no harm in listening to it from others. It is recommended to frequently remember Allah, to consistently recite the prescribed remembrances such as the morning and evening adhkar and those before sleeping, and to earnestly supplicate for forgiveness and well-being. It is also advised to maintain a regular portion of the Quran, understanding and contemplating its verses.
