I find when giving to patients using a slight angle (if they have enough fat) works, for skinny people sometimes the leg is less painful. Definitely pinching quite firmly before giving the injection and holding for a bit. Could your DH do it for you sometimes? or if you are at work a colleague, I think self injecting must be hard as there is the anticipation of the pain and anxiety about giving ait and knowing exactly when it will happen. I do think they higher doses sting more from seeing patients reactions, I worked in a cardiac unit for a while and a lot of pt's were on BD therapeutic clexane some up to 140mg BD for the bigger boys 'ouch'

Best of luck with your FET today.
