[55F] With sudden right leg swelling and back pain

What might be happening

Based on the information you’ve provided, there are a few serious conditions that could be causing your symptoms:

1. Deep Vein Thrombosis (DVT): This is a blood clot that forms in a deep vein, usually in the legs. Symptoms can include sudden swelling, warmth, redness, and pain. Given your sudden leg swelling and warmth, this is a serious possibility. DVT can lead to a life-threatening condition called a pulmonary embolism if the clot travels to the lungs.

2. Cellulitis: This is a bacterial skin infection that can cause redness, swelling, warmth, and pain in the affected area. It can develop quickly and requires prompt medical treatment.

3. Spinal Issues: Given your back pain and leg symptoms, there could be a spinal issue such as a herniated disc or spinal stenosis that is causing nerve compression, leading to swelling and pain in your leg.

What you can do

1. Seek Immediate Medical Attention: Given the potential seriousness of your symptoms, you should seek medical attention immediately. It is important to rule out conditions like DVT or cellulitis, which require prompt treatment.

2. Call 911 or Go to the Emergency Room: If you are experiencing severe symptoms or if you feel light-headed, short of breath, or if your symptoms worsen, call 911 or have someone drive you to the emergency room immediately.

3. Avoid Walking or Standing for Long Periods: Until you receive medical evaluation, try to keep your leg elevated and avoid walking or standing for long periods to reduce swelling.

4. Monitor Your Symptoms: Keep an eye on your symptoms. If you notice any changes such as increased pain, swelling, redness, or if you develop new symptoms like chest pain or difficulty breathing, seek emergency care immediately.
