Is there any way to get rid of the bumps under and around the veign caused by injecting Morphine Sulphate? Before you answer........great care was taken not to miss the veign, but it still seems to collect around and under the veign anyway if used regularly. Is this due to the veign not closing up right away? Great care was taken to close off the veign by adding pressure to the injection site immediately for about 5 minutes, although same syringe was used a few times (3 or 4) by the same person. However, when using brand new syringes every time, the bumps still formed. They are very solid and very hard to push the needle through, although one can still get a veign to register going through the bump. It is said to be non painful pushing through the mass, but it is of great concern to the user at this time. This is research for a friend.
