Title: "If anyone/someone could correct the false grammar?" or, "Can anyone/someone correct the grammar issues?"
She came to the hospital complaining of both legs swelling. It started one month ago with a gradual and progressive course, increasing during the day and combined with swollen eyes in the morning soon after she woke up. The edema started in her eyes then spread to/developed in her lower limbs, and it is most probably a renal edema. Neither fever nor weight-loss were present. Other symptoms include not being able to open her eyes when exposed to direct light or to the sun, *with 24 flushy cheek redness.*
This was one way of correcting it. The asterisks enclose the part of the paragraph that I don't understand; what's "24 flushy cheek redness" mean? Otherwise, not to bad. Your issues: tone (this seems to be some kind of medical report; keep a distance between the events you describe and yourself) and sentence structure (especially concerning tense; you go from present to past within the same sentence, and that's a big no-no). Otherwise, good work.
