Scitica isn’t a medical problem, but a symptom of one. Pretty much in order of occurence, these are sensations I experienced. Some of these may not be textbook or even sciatica, but hey, I they were symptoms and I’m not a doctor!:

• small, ‘sharp’ pain in the buttocks
• pain at top of thigh muscles
• aching hips (with hindsight this wasn;t a hip problem but the start of sciatica at top of thighs)
• pain bending leg
• very ‘stiff’ aching leg muscles
• Extremely strong shooting pains down the leg (strongest pain I’ve felt yet)
• pins and needles down leg
• strong pins and needles in foot
• pain in thigh (like a torn hamstring years ago)
• sandpapered calf muscle (as if the skin’s not there)
• numb toes
• numb top of foot
• decreased sensation in skin under leg
• pain ‘inside’ knee
• sharp to pain in rectum,
• tingling to dull ache in perineum
• dull ache in testes (like after being kicked in the balls)
• dull ache in lower back / base of spine (yes, not sciatica but I thought I’d write it)
