Tell me more about the picc line please. My doctor wanted to do that on my last visit - I held him off for another month.
I had one in for 3 months with my Lyme. They put it in your upper arm while you are awake (typically). They just give you some Atavan or something to take the edge off. It is uncomfortable and feels like a lot of pressure while they are doing it, but nothing unbearable.
Once the line is in, they will assign a home health care agency to you so that a nurse will come visit you once a week to clean and change your dressings. My meds were delivered on ice to my house once a week. They were these little ball things that had some kind of pressure delivery system so that you could wear them in this little waist pouch thing and move around -- it's not like you had to sit there hooked up to an IV pole. The home health agency will bring you all of the supplies you need each week. I bought one of those plastic 3 drawer things to keep it all in, so that I had everything I needed in one place and it was right there for when the nurse came. They really do try to make it as easy as possible on you.
Taking the line out is much easier. My doc just did it right there in his office. I really didn't feel much of anything, just kind of an odd feeling for a second or two while he was pulling (there's more in there than you think).
All of my physical symptoms have gone away, but I still have memory issues, as I had it for awhile before I was diagnosed. I originally had just severe tiredness (I couldn't go to the store, church or anywhere without having to take a 3-4 hour nap afterward), which passed after a couple of weeks so they thought it was just mono. After a couple of months, I had severe knee pain in both knees than a couple of months after that (with the knee pain still there) I started having memory problems, losing words while speaking, not remembering names of people I have known for years. At that point they finally tested me for Lyme and treated me for it. As I said, the physical symptoms are gone and, although the neurological symptoms are better, they are still there.
Both of my kids have had it, as well, but because I am so tick-phobic now and have them checked at the slightest hint of anything, it has been caught early with both of them. After the 28-day antibiotic treatment, they have both been fine.
Best of luck to you. I hope you are seeing someone that is knowledgeable about Lyme.
