Hello. Without a full history, I understand it is impossible to respond with confident specificity; still, I have dealt with sporadic lower back pains for about 7 years, and around the first of last May, the pain returned and was crippling; the worst it had been, without a particular, immediately precipitating injury. After a week, the lower back pain transitioned into sciatica in my left leg, although it is faintly present too in my right thigh and right ankle. The pain is now worst on my left ankle, but present too in my left shin, my left index toe is numb most of the time, and sometimes feels as though jammed. I have the burning patch on my left thigh, and the hallmark symptom of sciatic too--but I am now dealing with nerve tingling and soreness in my left arm, at times right arm, and in both hands--which also slightly tremor, my leg too if crossed--but these tremors are not new to this recent onset. I feel tenderness and pain at times in my neck/shoulder, left side. My stomach is constantly spasming, its persistent contractions distinctly visible. I am dealing also at times with jerky movements of my legs and arms, and sometimes my head. I seem now to frequently urinate with great pressure, but I do not feel urgency to micturate beforehand, and my bowel movements are now often difficult. It very much seems to be a comprehensive and progressing thing, and now rapidly so, affecting certain peripheral and motor nerves primarily.
