I hate needles. Would an insulin pump be easier for me than injections?

21 or 23g.: I agree that 25g may be unnecessarily small. 21g or 23g would be better. Pain comes less from the size of the needle and more from the technique of the injection. ...Read more

Hi me and my fiance are trying to have a baby and we are trying vaginally.... We was wondering if after a year could we try the needle injection?

Time for consult: If you have been having unprotected sex with your partner for more than a year & not conceived, a workup at a fertility center may be the best way to find answers. Both you & your partner will need to be evaluated. Your regular OB can sometimes start the process but the center can study you both & provide information on assisted pregnancy if needed. Costs vary with the procedures needed. ...Read more

Safe way to get a used needle out of biohazard container? Need the one they used for my injection to analyze needle contamination (microbes, viruses)

Safe way to get a used needle out of biohazard container? Need the one they used for my injection to analyze needle contamination (microbes, viruses)

Contamination: Don't do this. Once in that container it may well have been contaminated by other materials within the container, and the very reason these containers are used is to prevent you from being inadvertently exposed to the pathogens that may be within them. Analyzing the flora on the needle will be grossly misleading and an inappropriate means of data collection. ...Read more

I always contract my buttock when the nurse pushes the needle inside my buttock during b complex injection (per week). What are tips for painless shot?

I always contract my buttock when the nurse pushes the needle inside my buttock during b complex injection (per week). What are tips for painless shot?

It's mind over body: One's mind controls one's body. That means one can decide to give up control of the butt muscle for 60 seconds. During that time, the butt muscle is allowed to stay soft and relaxed, because the person has decided he will not send any signals to the muscle to move or to tighten up. That works, but one has to practice letting go of the butt muscle (stop controlling it) for a minute. ...Read more
