I have been injecting myself for over 25 years and have never had any problems. I have no lumps or dips and rarely bruise. In the last few weeks, however, I have suddenly developed strange little red, angry 'pimples' at the point where the needle goes in. It looks horrible and they are quite sore to the touch. I will mention it to my doctor next time I see him but in the meantime wondered if anyone else had had the same problem. Thanks.
