Lung pain

I've been vaping for nearly 15 years and I've never once had any chest or lung pain associated with it. Recently though, I have and I cannot figure out why. It really sucks as I do love to vape.

I build my own coils on an RDA. I have done that for 90% of the time I've vaped. Only using tanks for a while right when I started. A week or so ago I decided to try a different coil material other than kanthal for the first time, nichrome. It's ni80 which is, to my understanding, 80% nickel and 20% chromium.

I used a prebuilt Wotofo Labs fused clapton. I wanted to try the build before I decided to make it myself. I loved it. Better flavor than my twisted 28g kanthals ever gave me. However by that night I was feeling very sharp pains on the right side of my lungs whenever I would breathe in. It got really bad at one point, like 8/10 pain level. I thought to myself "what have I done different to cause this?" And my mind went to the new coil material.

After some thought and research into ni80 I remembered that I am indeed allergic to nickel. I know this from fake jewelry I would wear sometimes as a teenager which caused me to breakout in hives and itch. Fake jewelry is made with nickel, or at least the kind I would wear. My mother has the same allergy. So I changed the coils back out to kanthal and continued vaping.

Now, I'm not sure if it was the ni80 doing this. I read reports of people online also having reactions to it but they would say it also hurt their mouth and throat. For me it's just the lungs. So idk if the ni80 actually contributed to this pain.

While the pain did lessen and never rose back to 8/10 it wouldn't completely go away. So I switched to nicotine gum for a couple days and the pain left completely. But when I picked the vape back up with the kanthal coils the pain returned... I then decided to go see a doctor.

They gave me an x-ray but nothing showed up on it. She diagnosed me with pleurisy (which is inflammation of the lung tissue) and told me to stop vaping. So I went back to the gum. A day later I tried the vape again and it was fine for half a day then the pain returned...

I love vaping. And find It hard to believe that after 15 years with 0 issue it's all of a sudden causing pleurisy in my lung tissue. So I guess my question to you guys is, has anyone else had this problem? If so, did it eventually resolve or have you had to quit vaping altogether? Going to cross post this around to get as many eyes on it as possible.

Thank you to anyone who takes the time to read this long post and anyone who may have some insight. I really hope I don't have to quit completely but of course I will if necessary.
