This was found out after I started getting hives on the bottom of my feet and I had to go to ER for prednisone treatment. I was referred back to my GP and got some electrolyte workup, etc. that found the hypercalcemia. Anyhow I was prescribed several different antihistamines to treat the hives and they weren't very effective. I was waiting on seeing an immunologist to find out what was causing it in the meantime. Anyhow, I found that NSAID's (especially ketaprofen) were VERY effective in alleviating the itching and stopping the hives, whereas several antihistamines were relatively useless (Claritin, Allegra, Benadryl, etc.) I was under a lot of stress (cortisol connection?) during all of this time. Question is: IF I responded to NSAID's instead of antihistamines-does that "tell" anything about my HPA axis/cortisol "picture" that is noteworthy or remarkable in any way? I know that NSAID's act on prostaglandins. Are prostaglandins and cortisol linked? Thanks again for any info-your posts are very informative!

> I don't feel qualified to give you a definitive answer, as the interactions between the various products of cyclooxygenase enzymes are exceedingly complex. In general, COX inhibitors suppress ACTH (adreno-corticotropin hormone) and cortisol release. So, a non-specific COX inhibitor like ketoprofen will suppress stress responses. This will suppress, in turn, inflammatory cytokines like TNF-alpha. TNF-alpha can induce release of the inflammatory and urticaritic (hive-producing) prostaglandin D2. So, COX inhibitors can have direct and indirect effects suppressing inflammation, including hives.

Thanks for the response! I was primarily curious why on earth antihistamines were doing practically nothing, but one tab of ketaprofen nearly eliminated the systemic reaction (for a few hours anyways). The reaction was so bad at times that most of my skin all over my body was uncomfortably hot, with hives on my feet, and extremely itchy. Hydrocortisone creams helped somewhat, but only ketaprofen and prednisone worked quite effectively. The cause of the hives was found to be a severe dust-mold allergy that presented itself only systemically (1-3 days after exposure). Did immunotherapy for that (allergy shots) and it cleared up. The hypercalcemia "cause" was never found. I would get one test and it would be well above the normal range, get another test and it would be normal, then get another one and it would be only moderately high. Then it just went away. But just a few months after that was when I got my thyroid tumor. Hidden tumors are also a cause of hypercalcemia, so it may have been related to thyroid, but I didn't have any symptoms to suspect that, until my GP found the enlargement in my thyroid.
