Is this grammatically correct and what does it mean? “I rushed out so early that morning and I’m just coming back home now with serious migraine”

The sentence is mostly correct but could use a couple of minor adjustments for clarity and grammatical accuracy. A revised version could be: “I rushed out so early that morning, and I’m just now coming back home with a serious migraine.” **Meaning:** The speaker is conveying that they left home very early in the morning and are now returning, experiencing a severe headache (migraine). The use of "just now" emphasizes the recentness of their return.
