Not sure what they are treating you for.. All my tests came back normal. No one appears to test the cytokine activity which according to studies needs to be done. So I just opt to take the Zyrtec and Pepcid that have been used in the studies successfully to lessen Covid problems resulting from over expressive cytokine activity. The drugs are antihistamines that address the overabundance of histamines in the system related to the cytokine abundance. Hope that clarifies. Are they treating a specific symptom you are having?
