Hi there ~
I understand your concerns and the fact that you are worried about your symptoms to the point where you are unable to sleep. A visit with a psychiatrist
to consult the doctor about the possible medications that you can use to symptomatically get rid of these issues might be of help. I also believe that there is no cause for concern regarding the darting pains in your left breast, however you may need to do a breast self examination and have yourself be seen by a doctor to find out if you need a mammography
. For all that your breast symptoms may not be related to your use of cocaine. You may also need a per rectal examination
to determine the cause of bleeding, for which you need to consult a qualified doctor.
I hope this helps. Take care and have a lovely day!
