Potentially stupid question inbound: Is it possible to have an allergy for denim of all things? I have this thing when wearing denim where the back of my left leg is itchy/disturbed by something that feels prickly in my denim on my leg. I threw away a pair of jeans that I thought was "pricking" me because of a loose stitch or thorn inside that I could not locate when I turned them inside out and then...but I've realized in every single pair of jeans i have, at this exact same spot, on my left leg only, there is an itch/disturbance and that thorny feeling is there (even in a pair of jeans i just bought last week). My right leg is fine, but my left leg is just doing this all the time...I don't have this issue in khaki's, which is why I'm asking. For more info, I had this issue last year as well and an exema looking dark spot formed at the back of my left leg. Went to the doctor, they gave me an ointment and meds, I treated it, and when summer came it died away since I stopped wearing long pants in summer and therefore obviously no jeans...now that it's fall and I'm wearing jeans (or maybe it's something seasonal), the spot is reforming. I have a good amount of money invested in denim so this question is pertinent for me and future purchases. It's bothering me to fathom since how can one be allergic to denim and have any sense of style? -.- The concept of a denim allergy just doesn't make sense either...so I would like some opinions on what this could be. 6/7 different pairs of jeans can't all have loose stitches in the exact same area for the exact same leg so I'm missing something here. Thanks.
