**Core Concept**
Red degeneration of myomas, also known as hyaline degeneration, is a type of degenerative process that occurs in uterine fibroids (leiomyomas). This condition is characterized by a sudden change in the appearance of the fibroid, leading to its softening and shrinkage. It is often associated with pregnancy, particularly during the first trimester.

**Why the Correct Answer is Right**
Immediate surgical intervention is not necessary for red degeneration of myomas. This condition is usually self-limiting and resolves on its own with conservative management. The pain associated with red degeneration can be managed with analgesics, and the condition is typically not life-threatening. The correct management approach involves monitoring the patient's condition and providing supportive care, rather than immediate surgical intervention.

**Why Each Wrong Option is Incorrect**
**Option A:** While red degeneration of myomas does occur commonly during pregnancy, this is not the statement that is not true about the condition.
**Option C:** Interference with blood supply is actually a contributing factor to the development of red degeneration, rather than being the reason for the condition itself.
**Option D:** While analgesics may be used to manage the pain associated with red degeneration, this statement is not the one that is not true about the condition.

**Clinical Pearl / High-Yield Fact**
Red degeneration of myomas is a common cause of acute abdominal pain in pregnant women, and it is essential to distinguish it from other causes of abdominal pain, such as appendicitis or ectopic pregnancy.

**✓ Correct Answer: B. Immediate surgical intervention is needed**
