I can sympathise Lordna, and hope your symptoms soon improve – as with any other member suffering a similar condition.
We are all vertebrates – meaning we have spinal / vertebral columns composed of vertebrae ( 7 cervical, 12 thoracic, 5 lumbar, sacrum and coccyx ). The vertebrae protect the spinal cord, and each vertebra is “ cushioned “ by a fibrous disc. Because we are primates who have evolved an upright posture, it’s not surprising that back pain is a common problem affecting most people at some stage in their life. It’s not usually serious, most often caused by bad posture, and usually gets better within a few weeks by taking painkillers, keeping mobile, and staying positive in outlook

.
Sciatica is pain due to irritation or compression of the sciatic nerve ( which runs from the back of the pelvis down each leg ); a mild form may accompany lower back pain or it may be very painful. There may often be no obvious cause, or it may result from a “ slipped disc “ due to repeated back strain and increasing age.
Clearly anyone who has felt the need to visit their doctor with one or more of the many types of back pain – with or without sciatica - is worried, and finding it hard to cope with the pain. I’m sure in those cases the doctor will have given appropriate advice, after full examination.
“ Over-the-counter “ pain killers are effective for most people. For acute ( short term ) sciatica, drugs like ibuprofen ( an NSAID, or non-steroidal anti-inflammatory drug ) are effective, but may be unsuitable if you have digestive or other disorders. Buy the much cheaper generic version

. For longer term use, paracetamol ( acetaminophen ) may be used with or without codeine ( an “opioid or “weak relative “ of morphine. “ Co-codamol “ is such a combination. It may be bought from a pharmacy ( Co-codamol 8/500 = codeine 8mg and paracetamol 500mg ); or prescribed ( Co-codamol 15/500 = codeine 15mg and paracetamol 500mg , Co-codamol 30/500 = codeine 30mg and paracetamol 500mg ). There are cautions about using these drugs, like any others, because of side effects.
My personal opinion ? Exercise is helpful – not inactivity as used to be recommended. Physiotherapy may be helpful. Other drugs, and surgical treatment would only be on individual medical advice. I would not pay a chiropractor or osteopath to treat a condition which in most cases will get better anyway.
