Prayer Request

My grandfather is in the hospital due to swelling in his legs. He hasn't been well in awhile, but has been in and out of hospital a fair bit the last month to 6 weeks in particular. He's 84 years old, a war vet, and a tremendous person, and my gramma is working overtime to take care of him and their household. Those with faith - any prayers - and those who are more earthly in their bent, any thoughts - are appreciated. Thank you so much.
