Over the past few months I have been loosing my balance and falling over, usually falling backwards or sideways. I have a mussey head most of the time. Blood pressure is normal to low.I am 69 and have had sciatic nerve pain for about two years. This has been investigated, conclusion, degenerating facet joints lumbar 4 5 and Sacrum 1,left sided. I have had two lots of steroid injections and radiofrequency denervation. This has given relief for a short period of time. My walking has been affected greatly as I have left calf pain and leg pain on standing and walking, Consequently I have lost confidence in my ability to walk anywhere on my own.
