Breast lumpectomy comfort advice

I've had my dressing removed today but finding it too uncomfortable to wear a bra still. Also itching like crazy around scar and nipple is super sensitive. I have loads of extra bruising due to a haematoma which had to be surgically evacuated a week after the lumpectomy.

Im after advice to ease the soreness and tenderness. What I can put on it, what to wear. I currently have a cotton wool pad placed over the nipple to stop rubbing and chafing. I think a bra would give more comfort to the breast but I can't tolerate even my soft bras due to the bruising and swelling which is still an issue 

Thank you
