soft tissue swelling that moves to different parts of my body.? swelling usually shows up under instep or on individual finger or toe.This is not joint pain.Heel can also swell.I itch in the area that is going to swell,with swelling occurring within hours.the area will return to normal in a day or less.Itchy scalp is present during these outbreaks.It seems to be affected by pressure.if I use a tool that requires squeezing pressure it is likely to cause swelling in that area.
 I may have picked up a bug on a trip to Europe about 5 years ago.The out breaks started after I returned from that trip,and I was quite sick the last day in England.Chills ,profuse sweating that went away the next few days.These outbreaks happen maybe twice a year but I don't know what brings them on.
 Separate work related flare ups can happen randomly.Installing flooring caused the side of my hip and leg to swell ,chills came on later after the day was done.
 Hope somebody recognizes this.My Dr. says "keep an eye on it".Thanks joema
