<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a small bluish lump under the skin in the middle of my palm on my left hand. It is painful to touch and when open and close my fingers. I was digging in the garden a week ago but other than that no other activity. It has been painful for about three days  <response>: Hi. Thanks for your query and nice history. This is self-explanatory. The lumps are bluish, painful to touch and movements, garden work :: All this suggest this to be a small hematoma in a confined space-so is painful. It is expected to resolve on its own, provided you give a rest to the part, do not fiddle with it. You may take an OTC ibuprofen or so to reduce the pain and swelling. Wait and watch is the best policy.
