What causes a lump on lower back?
Patient: Hi, I have a lump on my lower back. I thought it was a pimple so I tried to pop it but it does not pop, just really hurts, especially when my book bag is on it. I believe I have experienced a bump like this before on my back. Would you happen to know or have an idea to what it might be. Doctor: Hi,It would be difficult to make a diagnosis without examination. However, this may be a sebaceous cyst or possibly a lipoma which is a fatty lump. If your book bag has be pressing on it, it may have caused some inflammation. I suggest you see your doctor for examination and further advice. Regards,Dr K A Pottinger
