Its been almost 2 months I have a round lump on my lower back near kidney side and when I press the lump I like on the bone but feels its inbetween a bone and quite squidgy. Its causing pain all over my back lower back and shooting pain in my left leg and my leg feels quite numb.. I have been to docts and gave me strong tablets to help but has done nothin I'm goin hospital today and also have doctors tommorow. Its really scaring me if anyone can help me thatl be great. I am worried what it is but dont want to assume the worse.
