Lump on buttcheek
Welcome to A2A, greeniiiz69. It does sound like the sciatic nerve is being irritated. There are a lot of possibilities for what it is, and it will definitely need a doctor to investigate. The doctor may call in a specialist. Most lumps on nerves are not cancerous, though they may require an operation to remove them; but occasionally they are, in which case the sooner they are dealt with, the better the prognosis.
So please get to a doctor as soon as you can.
