It may sound like a good idea for your skin and to save you money but I do not recommend reusing a syringe. Once a syringe is injected it is no longer sterile and there is a greater possibility of contamination. If you are experiencing lumps, they could be swelling from the injection. Swelling should resolve within ten days. I recommend that you wait until the second week post-injection and if you are still unhappy that you return to your doctor.
