What is the grammar error in the sentence: "Several lucrative careers, in the healthcare field, do not, however, require a medical degree."?

The sentence "Several lucrative careers, in the healthcare field, do not, however, require a medical degree." contains excessive punctuation that disrupts the natural flow of the sentence. The use of multiple commas creates interruptions, making it more challenging for the reader to follow the main idea. A cleaner structure would remove some of these commas, allowing the sentence to read more smoothly, as the direct message is obscured by the interruptions.

While alternatives may address other grammatical aspects, in this case, the primary issue lies in the overuse of commas, which detracts from the clarity and fluidity of the sentence. Simplifying the punctuation enhances readability and strengthens the communication of the intended message.
