Well the other day I bought one of those razor blades for scraping algae off because the stuff at the sand bed was making me angry. So long story short I had my arm in the tank for a good 30 mins. So here's the issue, due to an airsoft event my arm has literally over 20 mosquito bites on it and now my whole arm aches likes crazy! Feels like it is going to fall off and my hand hurts when I try to make a fist or move my fingers. Did I just poison myself? I've had my arms in the tank before for that long but never with cuts and stuff.
