Hi there I have a a moderate disc hernia at L3L4 level, not giving back pain but 6 monthes of gradualy increasing sciatic pain in r. buttock and leg. have now been off work 7 weeks, cant walk, sit or stand without severepain after 15mins up and about, but not actually limited in movement.Can you explain if the actual nerve may be swollen and being upright just worsens the pinch. Specialist has now given me cortisone tablets 5ay s only. It has relieved so far (day 4) but can it cure the irritated nerve.? could the nerve be swollen at the foramenal opening after 6 months of untreated abuse/bending and no rest or care?i don't want surgery! Im resting heaps now, etc with other conservative treatment. thanks, kay.
