Shingles Pain

Patient: I know that I have shingles because I saw my doctor. I wasn’t able to have the medication because by the time I was correctly diagnosed the rash had already started to appear. Without the medication, how long do I have to endure this pain? I am taking medication for pain but doesn’t completely stop it. My daughter is giving birth as I type this. I would like to see my new grandchild. When will it be safe to do so.
