A while back I got some new pine shavings from TSC. opened the bag up and it got on my arms had long pants on, boy did I start itching all over my arms, never had that happen before or since, didn't see anything crawling on me but just started itching like I was being bitten. But saying this I bought a bag of cedar shaving because I had read that it would keep snakes out of the duck coop this is before I knew better, well I was using my hand to pull out the shavings to spread them around when a brown recluse spider bit me on my pointer finger on my right hand, you talk about extreme pain, started out slow but by the next day I was at the Drs office with my finger swollen and so painful. we were really afraid I would lose my finger, had to take shots in the bottom and have dressing changed a couple times a week lost the nail but saved the finger. Sure don't want to ever experience that again. Hope you get over the itching quickly.
It could also be a plant in the area that's causing it... I know someone who is allergic to dandilions for goodness sake. So until you get an allergen test done you won't ACTUALLY know.
