Hi , thanks so much for sharing with us all. I'm so sorry to read that your psoriasis appeared after you quit smoking. It's really upsetting to do something that's beneficial for our health, only to have other issues pop up. You're certainly not alone in this experience - I have seen a few people in the wider psoriasis community say that their psoriasis started or flared up after they quit smoking (I've also seen people say that quitting smoking seemed to help their psoriasis). I hope others will stop by to share their personal experiences with you.
I was able to find the following case study, which I thought you may find interesting: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3325452/ The man in the study developed psoriasis after he quit smoking, and subsequently seemed to find relief with nicotine replacement therapy. There's also an interesting discussion on how nicotine can be immunosuppressive and anti-inflammatory. I should mention that there's also a lot of research to suggest that smoking can aggravate/trigger psoriasis. I think another big issue to consider in this situation is stress. Both mental and physical stress can be huge triggers for psoriasis. I know a number of people who smoke use it as a stress management tool. Similarly, the process of quitting smoking can be quite a big, stressful event.
Have you been able to get your doctor's thoughts on this? And have you been offered any treatment to help you manage your psoriasis? It sounds like you're dealing with a lot at the moment.
