I just had Botox injected for the first time over 48hrs ago. 56 units in total. 20 in each jaw line (I suffer from lifelong bruxism). 4 in each brow lift and 6 in my forehead. I developed side effects 6hrs post the procedure and they have not subsided. Noone knows what this is and I am struggling to know what I am dealing with. I have tender lumps. I cannot open my jaw more than one finger width apart. I've been prescribed prednisolone 25mgs but has not helped as yet. Help I'm worried!
