lower back pain - no tingling feeling in legs or arms (I had sciatica many years ago) but extreme pain when trying to get out of bed - cannot straighten up - I have to hang on to back of chair and slowly straighten up. Once I am standing erect, I can take some steps and after a few minutes I walk more or less normally. I feel I may have a slight inflammation in the tissue around my spine in the middle of my back. I am an 84 year old female, who until last week was happily riding her bicycle. P.S. I am hopeless on any computer !!
