How can i stop swelling in my hands and feet? is it from lupus or something bad like that?

Not all swelling bad: Swelling in the hands in the morning, or swelling in the feet in the evening is often due to water retention, and is harmless. Avoiding excess salt, and using support hose can help. Persistent swelling that is localized to joints, or associated with redness, warmth, or tenderness may be signs of arthritis.

Need an evaluation: Good question but you need an evaluation to verify the diagnosis the swelling of the hands and feet suggest arthritis but we need a complete examination including laboratory tests this will to confirm if you have a poly arthritis (arthritis in many joints) and the type of arthritis like lupus, rheumatoid arthritis and others. Swelling can also occur for non-arthritis reasons so thus an exam.
