When you applied ice directly to your upper arm near the shoulder area for 5-10 minutes, it caused swelling in that part.

The human body responds to cold exposure by constricting blood vessels and reducing blood flow, which can lead to swelling once the ice is removed.

If you were injured, it's likely the injury and the prolonged application of ice that caused the swelling.

Ice is usually applied to reduce swelling, but it doesn't always prevent it completely.

How Long Does It Last?

Swelling from ice application can last for hours or even up to a few days, depending on the severity of the injury and the individual's healing process.

Reasons for Swelling

Swelling occurs when excess fluids build up in the affected tissues, and it is the body's natural response to an injury or trauma, thereby aiding in the healing process.

Prevention of Swelling

To prevent swelling from ice application, it's important to use a cloth or a barrier between the ice and the skin to avoid direct contact, limiting application to 15-20 minutes at a time, and allowing the skin to return to normal temperature before reapplying ice.

Moreover, seeking medical advice if the swelling persists or worsens is crucial.

It's essential to be cautious when applying ice and to monitor the effects.

Applying ice directly on the skin for a prolonged period can have adverse effects, causing more harm than good.
