I've been to a doctor once already, they put me on scabies medication (wrooong~), then did blood work, and then told me they had no idea. (Cost me a pretty penny to get a no-diagnosis.)
I've had a reoccurance of the following symptoms on and off for the past year. It started (or I noticed) around last September, symptoms hung around for a month, disappeared until November, then I had it for several months, it faded out, and now it's coming back this November. I am a 21 year old female with no current physical medical problems. 5'5", 120 lbs. I don't get regular exercise, and I'm frequently using the computer.
On my finger tips of both hands and occasionally my toes, I'll get small splotches of reddened skin, ranging from pinhead to a centimeter long. Some are circular, some are just splotchy.
Each location is tender to the touch, with varying amounts of pain (Not bad pain, just irritating.) and some places will be have cyst-like protrusions with darker red spots that look like I broke some blood vessels. The area around my fingernails is inflamed and reddened as well, but without the pain.
My fingers will also get dried out around the time these symptoms occur, I suspect because of the light swelling at the locations and ebbing of that swell.
My right hand, my dominant one, has more of these splotches than my right, though the left side is more likely to get the 'cyst-like' protrusion things.
The locations of these splotches will change, and ebb-and-grow in intensity of redness size and pain.
When I get the splotches on my toes, they are the non-painful variety, mostly around the toe nails. I didn't notice I had them until the doctor asked if it was on my toes, too. (Good for something, I guess.)
It is not caused by medication, and I highly doubt it's food allergies or bug bites. I do not have any pets. I have tried the basic test-if-I'm-'allergic-to-cold by using an ice-cube and keeping it on my forearm for a long period of time, and there was nothing abnormal. I do not come into to contact with chemicals. My shampoo and soap has not changed in relation with the symptoms appearing.
Besides the above, I have not noticed any other symptoms. Anyone have ideas for what to investigate? I don't want to waste money on a wild goose-chase.
