The duration of telangiectasia is one of the most diagnostically informative features of any symptom. Acute telangiectasia lasting seconds to hours has different causes from subacute telangiectasia lasting days, or chronic telangiectasia persisting for weeks to months. Knowing the typical duration helps you judge whether your telangiectasia is following a normal course or warrants evaluation.

As a general rule: telangiectasia that persists beyond 72 hours without improvement, beyond 1 week without a clear cause, or beyond 3 weeks in total warrants medical evaluation. Context matters — a first episode with no other features is less urgent than recurrent or worsening telangiectasia.
Why is my telangiectasia lasting longer than usual?
Prolonged telangiectasia compared to your normal pattern can indicate an untreated underlying cause, disease progression, a new contributing diagnosis, or reduced effectiveness of your usual management. A medical review is warranted if your telangiectasia is unusually prolonged.
Can telangiectasia that has lasted months be treated?
Yes — chronic telangiectasia can be treated, but requires an accurate diagnosis of the underlying cause. Many people with long-standing telangiectasia have never received a formal evaluation. A structured workup identifying the cause enables targeted, effective treatment.
