It only ever happens now and again - twice a year or something, although it's not been that long since the last time and I've got it again.
It is very specific to my right front thigh - it goes all goose bumpy but really severe, the lumps are much more pronounced than normal goosebumps. Also they raise up, stay a few seconds and disappear - the sensation is like normal goosebumps. And they only appear in very definite patches on my front thigh. Any ideas? When I get a 'bout', it will come and go for a couple of days then go away for months and months.
