Im in absolute agony !!!!! ive always had back problems, but after my last flare up about 6 weeks ago i got sciatica!! i cant even sit down on the loo!!! my foot is numb and im waiting for an emergency appointment (referral) it eases up during the day, but night time and first thing in the morning are the worst. My buttock, knee,shin, calf, ankle and foot are all affected>
