I am a 43 yr old female with history of cysts (breast, ovarian, spinal).  I have small nodules under the skin on my upper and lower arms, near my elbow, also on my upper thigh and upper left side of abdomen.  These nodules appear like a bruise or \"black-and-blue\" and there is discomfort when pressure is applied to these nodules.  Are these blood clots or what are they?  What type of treatment would be beneficial?  Thank you for your time.
These may be neurofibromatosis with nodules formation around the nerves which appear as blue-black in color, cystic and tender on applying pressure. Nothing is to be done until it disturbs your daily routine because they are recurrent and can happen at all the site where there is presence of nerves. If it disturbs your daily activity, excision is required otherwise any anti-inflammatory or painkillers will suffice the need.
