I am 160 days (just over 5 months) post and I still have quite a swelling on sides of my nose and the tip. Shall I be concerned?

Hello. Great question. It can take up to one year for all the swelling to go down. Keep following up with your surgeon.

Hi and welcome to our forum!
The performance of rhinoplasty involves the separation of the nasal
bones and cartilages from overlying and underlying structures, fracturing
the nasal bones, removing excess bone / cartilage, reshaping of the
remaining bone and cartilage. The significant intraoperative trauma
causes swelling (which may be asymmetric), which will make your nose look
large and wide. This will improve markedly over the first 6 weeks, but will
take at least a year for your nose to assume its final shape and size. The
nasal tip is notorious for taking the longest time.
Your reaction to red wine may occur as alcohol causes intranasal swelling, leading to dilation of blood vessels. The phenomenon should not be permanent.
Consumption of alcohol in reasonable amounts is not contraindicated.
The presence of intranasal blood clots 5 months after surgery is not normal and requires investigation. 
Continue followup with your surgeon.
Best wishes...
