are we more likely than others to get RSD?

I injured my thumb over the weekend and a small but deep chunk was bitten off by a hinge. It's small, like half an inch diameter, but conical,like an upside-down volcano. I went to an ER and was given a tetanus shot and antibiotics and told to just put bacitracin on it and I'll be fine. Nothing to stitch because it was too wide.

But just changing the dressing tonight--this is day 3--had me, literally, in tears, sobbing in pain. I'm not a crybaby, but it was as if my thumb was stabbed down to the bone. It looks clean and all, but the pain is way more than I'd expect. It was just excruciating. Now it's calmed down and is just throbbing.

Does this sound normal for this type of injury--kind of a deep small bite of skin? Or is this because of neuropathy, and am i at greater risk of RSD? I googled preventing RSD and came up with Vitamin C.

If anybody has any suggestions, or knows if there's more prevention, I'd like to hear.

It's really pretty small, but deep. I'm on 5 days of Keflex.

are you sure it isnt infected. i had a puncture wound in my finger which when it became infected throbbed and the pain was pretty bad.

I accidently ripped a part of my nail off my thumb recently doing a "stupid" thing. It was a horrible pain for a WEEK.

RSD is a sympathetic neuropathy, where something activates the sympathetic nervous system. There are papers showing it can be prevented (trauma and surgical trauma RSD was blocked by simple Vit C treatments). It also responds to antioxidants, and seems to be some sort of biochemical signaling error. Also there are papers that calcium channel blocking drugs can help in the early stages. This suggests a malfunction of the NMDA receptor which is activated by calcium.

There are some patients over there with a crossover to PN but not as many as you'd expect.

I do think PNers feel pain more than other people when injured. This may be more of a link to Fibromyalgia than RSD.

I placed a small strong magnet over the nerve at the base of my thumb/wrist and the pain stopped. Without that little help that thumb was throbbing away and driving me nuts, especially at night. Certain positions in bed made it far more painful. I experimented with it some, since it has been a long while since I had an accidental injury of this magnitude!

In my line of work (locksmithing) I constantly injure thumbs & fingers.
I also have some sort of a condition where my skin splits along the fingerprint ridges and goes very deep. These injuries prevent me from playing the guitar or banjo for a month or so, every time. They hurt quite a bit. Sometimes its infection, others-just really hurts (fibro? RSD?).
I use anti-bacterial ointments, A&D ointment, and a dynamite herbal ointment I found in a health store (recommended by the owner) that really helps a lot in many instances.
But I always am exposed to dirty locks, dirt, cleansers, oils (WD-40), grease, etc.
This does not help the cleanliness of the hands.
I have to carry band-aids in my wallet all the time.

Yes, those split fingertips occur in printers and masons too.

When the skin gets defatted by solvents, it cracks.

Aquaphor ointment is good, too. There are cotton gloves you can wear after putting on the ointments --they are called Dermal Gloves, and sold in most pharmacies. At least they can order them for you, if they are not on the shelf.

Making sure you eat enough good fats will also restore your skin faster and keep it more resistant. Flax oil, especially. Rubbing evening primrose on the skin also works. It will heal and also prevent.

I think this feels like a root canal without lidocaine, so I'm going to load up on Vitamin C to prevent RSD. Also, I'm seeing a surgeon this afternoon just to have it eye-balled. I don't think he'll say anything special, but I'll feel reassured to have read advice on how to care for something this deep. I don't have a lot of faith in the PA who saw me in the ER on Saturday, so I'll feel better with an MD looking.

I have strong magnets that someone on this site recommended years ago, so I will try them tonight and see if they help me get a good night's sleep.

Thanks, Folk.

hands DO hurt horribly when injured, because of the high density of nerves in them which gives us excellent touch in our fingers. Sounds awful, hope the pain improves soon.

I think one of the definitions of RSD (someone correct me if I am wrong) is that the pain continues long AFTER the injury has healed, and is not linked to the severity of the pain of the actual injury. I used to have RSD, but mine eventually improved which I know is very unusual.

hope the pain eases up soon

Had no idea Nitrous oxide gas induced neuropathy. I had it twice. For replacement of fillings and then for placement of front crowns.

I will keep this in mind. Thanks for the information.

Was this before you were Dx'd with PN?
If after, did your Sx become more severe?

I was officially diagnosed with neuropathy only last Winter through skin biopsy. However, the symptoms I have been experiencing go back 17 years. So my illness was already apparent prior to receiving the N2O. And no, I don't think things became more severe. I do have severe episodes, but I can't attribute them to N2O.
