All in All you do need to go in to your physician's office, when you see the leisions, so that if it herpes they can do a culture. If it is a wart they can remove or give local topical treatment.
Good luck with the rest of your pregnancy
I hope this helps and good luck.
Hope this helps.
the other reason for the back pain maybe muscular skeletal and you may need to just have some adjustment with a chiropractor after having your baby and due the pregnancy and the change in your posture during pregnancy. I would start there first.
