Does shingles have other symptoms besides plaques?

Hello, for the last 4 days I have had a rather large plaque on the underside of my right breast. I went to the pharmacy earlier to get some canestan while it was a fungal infection but a little voice inside me told me to ask the pharmacist's opinion first, which I did! When I showed her my plaque, without hesitation, she told me right away that it must be shingles. I'm 33 weeks pregnant and I have to admit that it stresses me out a bit. I know that it is not dangerous for the baby and that they don't give anti-viral drugs for more than 3 days On the other hand To accompany my plaque I also have a pain in my right armpit permanently but it is not sensitive to the touch, not swollen and not red I also have a strong migraine and a stiff neck that goes down to the middle of my back which makes it difficult for me to walk since each step I take the blow that my heel gives to the ground seizes me with pain in my back. I don't know if it's clear hahaha My migraine gives me nausea and even prevents me from eating, which is not ideal when you make a human. Do you have any tips for me while waiting to see the doctor. thank you very much and sorry for the novel
