What Causes Sudden Weakness In The Legs?

I have had at least 4 episodes of a sudden weakness (almost feels like a rush) in my l legs. Kind of even in my buttocks down. If I did not have somewhere to sit I would collapse for sure. I sit for maybe 5 minutes and it goes away but I can still kind of feel a weakness. I am taking Macrobid for a UTI and other than that I do not take any medication. Last night I did take an Advil PM 200mg because it helps me sleep but I do not do that but maybe once or twice a month. In 20013 I had a L1 fracture. It healed ok but I do have a lot of back pain. I do not like taking anything . I do stretches and I have been doing PT for back pain. I am going to have a Thyroid Biopsy on May 4 because the Dr. saw some nodules that were dense???

Hi,

Causes of your difficulties may be neuropathy or ischemic issues. Neuropathic are seen in diabetics or injury of spine nerves.

If this is not your case then these symptoms are indicating circulatory problems in legs which are common in this age and there may be present atherosclerosis that obstructs blood vessels and causes pain and blisters to form.

You should do Doppler ultrasound of the leg or CT angiography to rule out such obstructive changes and then it can be treated properly by medications or by surgical and radiological procedures.

Also, you should have Aspirin and have elastic stockings applied, and should avoid cold environment and long walks. In most cases it can be managed with medications but sometimes surgery may be required in severe cases.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
Dr Ivan R. Rommstein, General Surgeon
