@livininthestix I had mine on and off for more than 20 years; for me they were a marker for the intolerance to gluten (celiac triggered later by H1N1). I also had itchy skin rashes. Irksome putting one's arms down and feeling the lumps. It is good that your doctors are ruling out the dangerous culprits. If additional inflammation and other tests come up negative, consider an elimination diet to see if your are sensitive to some food(s). There is no good test for non-celiac gluten sensitivity. My celiac panel test was negative, but I tried gluten free afterwards and my rash, lumps, and GI and reflux problems went away (GI in days, rash and reflux a few months).
