Could The Intense Leg Pain, Coldness, And Numbness I Experienced After Pneumonia Be A Sign Of A More Serious Issue?

I have just gotten over pneumonia, after getting out of the shower, my legs got intense pain. My ankles and feet got very cold and were asleep. I haven’t ever had such leg pain, and with that pain, I noticed the feeling of asleep was moving up my legs to my thighs. I’ve never had this previously, the pain was so bad I wondered if there was a worse problem. It was the most painful thing I have had in my legs. Because I have lymph edema my legs are swollen, but usually don’t hurt.
