Thanks so much for replying
I had mechanical traction. The first two sessions of traction left me feeling fine. No adverse after effects at all. The third session like the first two sessions,which went for 20min, involved alternating a heavy weight with a light weight, but this time he increased the time the heavy weight was on from 30sec to 45sec.
The symptoms recur usually annually and I think I can confidently say that it is becauses of increased work load and/or stress and/or poor posture. I usually have the symptoms for about 3 months and the a 12month break.
From your reply it sounds like this is not a common response to traction?
