Plegridy injection site

[Trundles77]

Hi all I am now on my 4th plegridy injection so far so good (much better than tecfidera which was horrendous for me) only side effect is the massive red swollen lumps on my thigh which seem to improve just before my next jab is due!! Question is can I just rotate between thighs for my injection sites I don’t really feel comfortable doing it anywhere else! Last 4 have been thigh but is this harmful? I do move the actual jab site around so hopefully not going in the same hole! Thank you for any advice x
