I injured my back a few weeks ago and had time of work as it was quite bad and couldn't walk , a few days later I developed sciaticslokeboain down my left leg/hip which comes and goes . I went to the doctors as I also have a limpoma at the bottom of my back which may or may not be linked (awaiting scan ) although the limpoma has gone down. I am still experiment lower back back and the scistisclike pain down my left leg, sometimes it is there ,bbit other times it is fine . I have been doing exercises to help bib that does not seem to last long . Sometimes the pain is unbearable but then other times there is no pain at all. Unsure what I should do ?
