I have Sarcoidosis for about 33 years. I just started a bout off shingles ( my third time)on my right breast under my arm and back on the right side. I take CBD oil for pain which helps.(legal in Canada) I am taking 30mg of prednisone which my Specialist prescribed me some time ago for my lungs. The pain can be very sharp at times and sometimes it itches. I put colloidal silver on it to help for the itch. Would the prednisone help with the shingles.?
