Hi welcome to health care magic forum,
Swelling of helix of right ear with cystic consistency without pain or discomfort indicate haematoma
auris. It may be spontaneous or post traumatic.
It is due to accumulation of blood or serum/fluid.
Haematoma auris usually painless . Secondary infection may cause to pain.
But it is unusual to peel the skin.
In my opinion you can take a broad spectrum antibiotic and antihistamine with an antinflammatory medication for 1 or 2 days.
But if no relief ,I would suggest you to see an ENT specialist
for thorough clinical examination.
