30year old cauc. female five months pregnant, have had several small (1/2in or so) in size hard lumps below the skin on the lower portion of my left arm, recently noticed two more in my right arm, right about the same position as the first two in left arm. History of spinal hemangiomas with same feeling lumps occuring around spine several months after spinal tap and blood patch. Can the two be related? primary care thinks the are lumps are fibroma however the newly occuring ones have me a bit concerned
