Brief Answer:
Use warm compress, avoid pain killers, see doctor

Detailed Answer:
Hello ma'am and welcome.

Thank you for writing.

I would like to start by saying that when there is numbness, swelling and pain in only one leg, it might be considered an emergency situation only because it can be related to a stroke; but this could be unlikely due to your age. Although I would still like for you to visit a doctor at your earliest convenience.

For now, please apply a warm compress, which will improve the circulation in your legs and reduce swelling. Avoid the use of pain killers for now, as one of the possible causes could be a kidney condition, and the use of pain killers will only make the kidney condition worse, so we will first have to rule out any kidney abnormalities.

I would like to ask you if you have experienced any insect bites off late? Any injury to the leg? Any burns, application of chemicals on that particular leg directly? Any changes in speech, concentration, vision, etc?

Now I shall list the possible causes for such a presentation:
-Circulatory problems (would require a doppler ultrasound scan of your leg)
-Kidney conditions (blood test to check renal profile)
-Physical examination (to look for any insect bites, burns or injuries)
-Medication (side effects of medicines, but you have not mentioned any medicines in your history)
-Brain or nervous system related conditions (these should be considered only after all other conditions are ruled out)

I would kindly request you to visit your doctor who will rule out more serious conditions, and also help relieve your pain and swelling at the earliest. Please feel free to write back to me for any further clarifications ma'am.

Best wishes.
