my husband has a spot on his foot that looks like a sore, his feet feel as if they are on fire, a place on his thumb which also will not heal. Blood work lately
I had the same problem for a year. It was bed bugs. The thing is my husband slept next to me every night and not a single bite. We checked our bed many times, even got rid of the mattress and box springs and bought new but still sores on hands and feet that itched.
Try this. cover your mattress and box springs in zippered plastic covers, pillows also. Then detatch your headboard from the frame of your bed and move it out from the wall. Spray the frame with any bug spray containing pyretherin. The wrap the legs of your bed in double sided carpet tape. It seems like a lot of work but if your hands and feet itched like mine did and the sores were so embarassing it is worth a try as we found out that was our problem. Bed bugs are very common anymore as the bug killers they used to use that caused cancer do not kill the bed begs long term. We were cleaning out some baskets one day and here were the bed bugs. They can live in alarm clocks, lamps, behind wall outlets and more.
If you find it is bed bugs, bad news is you have to have your house exterminated several times and they suggest your "island" bed for at least one year at least as bed bugs can live 18 months without a blood meal. Nasty little critters.
