Are you diabetic?

Gout is very painful and causes swelling.

Great suggestions here. I would also like to add that the swelling in your feet could be due to heart
Issues and I would be seen today! Please don’t put it off and let us know how you’re doing!

Sounds like it could be rheumatoid arthritis.

Yes, but is almost always confined to a single joint

Not really

Definitely see a Rheumatologist. Have your primary do labs: C-Reactive Protein, Sed Rate, ANA, Rheumatoid factor, CBC, CMP, Urinalysis, Venous Ultrasound, Ankle/Brachial Index or the equivalent. Consider POLYMYALGIA RHEUMATICA as a possible diagnosis.

You might have rheumatoid arthritis, check with a rheumatologist.

How much do you exercise? Could be from a weakening heart.

I have the exact same problem. I have heel spurs that cause plantar fasciitis. You may need orthotics.
Exercise the instep of your feet by placing a cold water bottle on the floor and roll your foot over it.
Stand on a step with your toes and stretch your Achilles’ tendon.
Take anti inflammatory pill if you can.

Go see an urgent care ER if you can’t see a specialist in the next couple of days!

Make an appt with Shands or the Mayo clinic for a full workup. Our Villages health doctor never found out what was wrong with my husband and over 2 years he kept getting worse and worse. We went to Shands for a full workup, he had Parkinsons, no shaking, but falls and difficulty walking, and had had it they said for about 5 years. They put him on meds and his physical abilities improved greatly. He died 2 years later, but thanks to Shands physical his last 2 years were not terrible. Go to Shands or Mayo clinic, do this for yourself, especially since you live alone. Good luck to you.

this may sound nuts, but the weather can do this to me. i have severe arthritis & spinal fusions-when there's unsettled storms, i can barely move. the last 2 weeks have been uncomfortable

poster above me recommends Mayo---i agree

Not a bad thought but PMR is not usually confined to the feet and doesn't have a lot of edema

Peripheral edema without dyspnea on exertion---not likely and also not painful

Plantar fasciitis in BOTH feet at the same time and again with edema---unlikely
