My coffee shop allergy

I have found a strange noticed lately, and this has in the last few months happened. I love coffee and coffee-shops and was since work for me I often go, check written work for errors, somewhere way only on my own, and are among the people of the phones and meet other distractions.
Recently, I've also found that I've started to get mild one asthma attack, if I go to coffee shops. I don't think much of it at first, a quick puff on the inhaler and I was OK, but leave the coffee shop brings instant relief.
At first I thought it might be, cross-contamination with milk or cream in my coffee or herbal tea, but since my suspicion of arose, I just like a hawk, making sure that I let staff know, so you make sure you are you carefully. I've seen that people stirring the same cups of coffee with the spoon as of a milky before - that would be enough to give me a mild reaction in the past. A mild reaction asthma and mild swelling of the lips and mouth.
I know that my dairy allergy dose with reference, so I have only a mild response to a trace amount of e.g. asthma, stomach cramps and maybe an evil red rash on my cheeks. But I recently I if I'm still sensitive always.
Could it be that I am responding to the oblivious latte and hot chocolate Slurper on the neighbouring tables? Foaming and heating the milk makes it more allergens? Has someone else with a dairy experienced this phenomenon in the vicinity of steaming milk allergy?
I together finally when I wash from an empty milk carton for recycling put two and two; (my husband drink milk, so we have it in the fridge) if I removed the lid to it dive into the warm soapy broth I got a taste of rancid milk. Not nice at all times, but on this occasion I had asthma attack immediately rather badly, my lips began Upselling opportunity and had to leave the room and sit down. A minor panic, all good to end, but that made me believe "It is the milk steam is doing this." "I have super sensitive to milk be!"
It seems that the milk, that impact is always a me, or steam touch right above of the nose; I seem to be good, if the drink in the traditional English way with cold milk added.
So do to I'm? Never again to relax in a café or a coffee shop? Maybe a should a mask when in such institutions? Or perhaps visits limit my Café in summer if I can sit outside where the evil vapours are scattered more easily? What a shame that away the time in a cafe in the winter with condensation on the Windows, cosy and warm just would the world as people to observe and cosy of go is a rare treat. There are dairy free cafes?
I was always aware that some people have such severe allergies, that be consumed even in a room with others the allergen, but this never happened to me before. Has anyone experienced the same? What should I do? Stop to expose of me in dairy in coffee shops? or go but for shorter visits? Can I perhaps desensitize me? This is probably unlikely, because I get if I even a small amount, I always by error and when not carefully enough have consume when ordering food anaphylaxis from milk. My attacks are usually aggravated by exercise, so this is a new feed for me.
I would love others with an allergy to the smell or only will be heard in the vicinity of allergen. How you done with him? My House is now a free zone milk? Maybe my husband can have its own refrigerator in the garage where he can have his breakfast and cup of tea I'm sure he would love that! It happened so far has not with only another Milky drink in the room, but it is only a matter of time? or am I only panic about nothing?
