you need to talk to your GP, it could be allergy, usually people do not have much pain where they inject, it is important though to inject where one has a lot of fat ... I myself have allergy to ozempic; probably some of the preservatives in it, it starts like 20 minutes after injecting and stops after around 4 hours , where I feel numbness in my face spreading to different parts of my face with the feeling like when the sedation is lifting at the dentist, like itching but no swellings... I have discussed it with my GP , and we both wonder why I am not swollen and red and sore at the injecting site.. yours could maybe be a contact allergy locally, but you need to have your GP evaluating it..
I am sad I have to give up Ozempic.. but I don't want to be afraid for a day every time I inject every week from now on, afraid that the allergy will develop to a more severe level and eventually could be life threatening. Allergy is rather seldom till now with Ozempic, bur it has also only been on the market for a few years , and all side effects might also not have been sent in to the company..
