Last week I woke up with severely itchy bites and rash from head to toe. I looked for every sign of a bug infestation but there was nothing. I itched till I bled. The itching and bites have mostly cleared now but my veins in my legs and feet are now extremely visible and there is a place on the side of both my left foot and keg that feels like a bug is crawling on me but again... NOTHING is there. 3 days ago about 5 hours after I left work on a shipping dock both of my hands swelled up and all of my fingers as well and it s still the same right now and feels like they were bludgeoned with a hammer and pain now going up my wrist also. Also have been having severe chest pains and shortness of breath today. I have no idea what is going on
