|My lovely Iontophoresis patch on my heel.|
Iontophoresis (a.k.a. Electromotive Drug Administration (EMDA)) is a technique using a small electric charge to deliver a medicine or other chemical through the skin. It is basically an injection without the needle. (My emphasis)The technical description of this process is a non-invasive method of propelling high concentrations of a charged substance, normally a medication or bioactive agent, transdermally by repulsive electromotive force using a small electrical charge applied to an iontophoretic chamber containing a similarly charged active agent and its vehicle. One or two chambers are filled with a solution containing an active ingredient and its solvent, also called the vehicle. The positively charged chamber, called the anode, will repel a positively charged chemical, whereas the negatively charged chamber, called the cathode, will repel a negatively charged chemical into the skin.
I stopped my my PT office and my therapist put the dexamethasone on the neg. side and a solution (I didn't ask what) on the positive side. It took about 10 minutes. I have to wear it for 24 hrs. My PT said it would take about 3 times before I started noticing a difference. If the patch doesn't stay on-since it's on the foot/ankle- I might have to do the wired version which would require me to stay at for 20 mins at the pt office. Hopefully this will work! I'm much calmer going into my Dr. appt tomorrow knowing I won't get a cortisone shot.
Edit: Had my Dr. appt today- told me to stretch more. Wow. That's why he gets the big bucks.- He did offer to give me the cortisone shot, I politely declined (for now). Having my pity party- PF sucks.
