I had an ingrown toenail about 6 months after developing RSD.
Never really thought much of it until it got infected so had to call my PM Doctor.
His advice was to take antibiotics and hope the infection would clear but it didn't, it got worse.
After a short while I saw a General Practitioner who told me that i'd need to have it removed surgically has it had got so bad.
My PM Doctor made sure the GP was informed on RSD and I was booked in to have it removed a few days later.
My Doctor knew it'd cause more pain so it was aranged for me to stay in hospital overnight where I was put on a Morphine pump to help control the pain.
Because of my RSD, the toenail was removed under general anaesthetic. We all thought the procedure would go well but it didn't. Upon waking I developed severe Myoclonic jerks in the same limb. No ammount of medications would control them and my Doctor was shocked as he had never seen anything like that happen before.
The spasms have settled down a little now, however I still have them.
I don't say this to scare you, just wanted to inform you of some of the risks. It is better to stay away from surgical procedures on an RSD limb if at all possible so i'd get it treated as quickly as possible so it isn't as invasive.
After the toenail removal, I was told that my RSD limbs are super sensitive and that any needle in them would cause problems (had a nerve block and lost all my coordination). Hopefully that wont be the case with you.
Speak to your treating dr and make sure he advices whoever performs the removal on RSD.
I hope everything goes well. If you want to talk i'm here!
