Hi,
I woke up this morning with a bright red patch of skin on my right thumb. The area is the length of the metcarpal bone and about an inch wide at the base about 1/2 an inch at the top. The size of the area has not increased or decrease since this morning.
There is no joint or muscle soreness, although the thumb joints were a little sore on Saturday. There is also no apparent bite mark. The area is not blistered, itchy, tender to the touch or sore. Any thoughts???
