Hello all. I am a 63 year old male and "out of the blue" have recently been diagnosed with SUB cutaneous lupus. My biopsy and blood tests confirmed I am R.O positive. It all started with a skin rash on my arms that i thought might be coming from chemicals in paint i was using to touch up some doors and skirting boards. After a number visits to my GP and eventually a consultant I have been told that I have photo sensetiviy and apparently my rash is being triggered by the sun and bright lights.This is after spending all of my life enjoying sun holidays !. I am trying to understand the underlying triggers as to how I would have contracted this photosensitive issue. I have had a number of stressful situations in recent years and in 2016 my Brother passed away having been diagnosed with a brain tumour 12 months earlier. I am thinking this might have been the final trigger. I would be happy to hear from anyone who might be in a similar situation and if they have improved their situation through diet/exercise /medication. I have been told to stay clear of the sun but this is almost impossible. I was on a sun holiday in recent weeks as it was already booked prior to my diagnosis. While I remained under an umbrella for the entire holiday,never the less, a rash flared up on my back and chest. Could thus have been triggered by heat as opposed to direct sun days ?
