Hi Jendays. I am glad your appointment went well and that you have a plan of action. Is your doctor going to address co-infections?
Getting a PICC line seems overwhelming, but it really is not. The line can be placed in a doctor's office or outpatient clinic. You will feel a stick, when they put it in but it should not be bad. They will thread the line up and then X-ray it to make sure it is in the right place. Usually a nurse will show you how to infuse your meds and will supervise you until you are comfortable doing it on your own. The most important thing is to be sure to keep the line clean and dry at all times. An infection can be trouble.
It is good to get a cover so you can shower without getting the site wet. One place you can get one is Brown Medical https://www.brownmed.com/Products/StoreProductDetail29.cfm?StoreProductId=99 You can also check at local pharmacies and hospital supply stores.
It can be very helpful to keep track of your symptoms during treatment. One easy way to do this is to list the main symptoms you are having each day with a numerical rating of their severity from 1-10. Over time when you review this, you can see when your herxes occur and how you are responding to the meds.
Good luck with your new treatment. Keep us posted on how you are doing.
