Sudden severe pain and sciatica in leg

Hi everyone. I had a TKR in May 2015 and though difficult I've made progress over the last months and although my knee swells now and again it is generally free from any pain. Today, out of the blue, I've had severe pain in my leg from the new knee area itself down to the ankle and up to the hop and lower back. I've been trying wading in swimming pools a few times whilst on holiday in Spain (I can't swim) as I heard the exercise would be good. Could it be I've done something? I've only done half an hour a day doing this wading with water up to around my waist or just above. I'm very disappointed as I've had no pain like this in my new knee/leg since the op 16 months ago. I did have sciatica trouble before the op and have spondylosis in the lower lumbar area. I'm also waiting to get my other knee replaced as this is causing much pain including referred pain to the hip area. I'm very disappointed!

Me too..

Read the sciatica section...

Have it looked at and get MRI or whatever they need to make sure they can find out what is going on.

I'm super sensitive to my own predicament, but my shingles started with minor soreness/ache in my quad thigh area. I assumed I had overdone

my recovery exercises. The skin lesions appeared 3-4 days after I noticed the soreness.

Ask your doctor to rule out shingles. Early anti-virals may lessen the ordeal.
