I took it about 3 days before & still taking it 2 days post op & will do for another week! Worked for me ive got no bruising at all, some swelling but that’s expected! You can get it from boots hun it’s only a few quid, you just let them dissolve or chew the tablets, first doseage is 2 every 2 hours for 6 doses (first day) then two 4x a day from then on until it’s got better!
