What is the risk of a minimal lung base collapse becoming a full lung collapse? rt lung base minimal collapse hypertension tachycardic at times

Unlikely to progress: But follow up with your primary care physician.

Concerned: Am concerned with 17 year old, "lung collapse", hypertension, tachycardia and arm pain. This needs very careful assessment. If the "collapse" you speak of is a pneumothorax, it would not be described as "asymptomatic". Thus would need further evaluation and potential intervention.
