I'm a 27 year old male, generally healthy, here is my problem:
For the past few weeks I've had some lower back pain on the left side. Today I noticed that when I touch a certain area on the lower left side of my back (just under ribs) I feel quite a bit of pain. It doesn't pain much on its own unless its touched. The pain goes some what to my left side. My feet seem to be quite cold most of the time, and there are times when other parts of my body seem cold. I don't know if this is related but I also have two spots on the backs of my calves where the hair has fallen out. Any ideas on this would be very appreciated! Thank you!
