Hi Linda,
Yes, the stabbing pain is nasty. I have had the stinging beasties off and on for the last 10 years but they do not seem to predict an attack or a worsening of symptoms in fact almost the reverse!?? The last 18 months I have had terrible pain (beyond 10/10) lying, sitting, standing, walking and on the skin all from spasticity. During this time when I was having my worst deterioration the stingers were relatively quiet. Now, I have a baclofen pump which has given me miraculous relief from all that pain and I am feeling good again but the stingers are back in my good leg & arm where they have never been before. I have found that rubbing them vigourously is the thing that helps the most. I also feel that they might be related to allergies but have managed to prove that. Hope you find relief!
