Doug Fir an allergen?

Don't have the MSDS :) but I've certainly never had any reaction other than sawdust odor makes me sneeze more than some others. Most conifers have enough pitch that may bother some people but old Doug Fir would be pretty unlikely culprit I'd think....

Believe I'd probably ask for medical opinion if it doesn't clear up on its own shortly...

Infection is not allergy, as you know. However, it is a real common thing for a tiny splinter to develop a bit of festering pus if neglected, and DF has a bunch of those available.

You were cutting old wood? Had you considered spiders or mites?

As you may already know, a dose of over-the-counter Benadryl will usually knock out most minor alergy symptoms. If that spot is a hive, the next time you get a similar reaction it could be worse, so I agree about getting that medical opinion.

...

And a dose of Benadryl knocks me out for the day, too... :(

I pretty much ruled out a spider bite, but mites I hadn't considered. There must have been a thousand of the little guys in lowest level of the stack... A testament to how slow this house is coming together.

I managed to get in to see the new nurse practitioner at my Dr's offices yesterday afternoon. She's very cute and lacks the bad attitude I've come across while dealing with most NPs at my PT job. She agreed that the affected area could be a developing cellulitis and put me on Keflex (antibiotic) as a precaution.

Thanks for all the input.

it can be. I've had DF splinters get nasty, and the dust is a mild irritant. it takes quite a bit of it to set me off, but with enough exposure it does.
