That kind of limited exposure would not be expected to cause any toxic neurological damage
It could easily however, trigger a migraine, in someone predisposed to migraine (and you are the right age group/gender)
Migraines can be triggered by smells, foods, weather etc
Other causes of headache and focal neurological symptoms should be excluded as they have done, then the diagnosis of migraine is more comfortable. You should continue to follow with your neurologist for migraine management - and in case the symptoms do suggest something else over time. Treatment is available to reduce the frequency of attacks if they are frequent.
The antibody is still fairly low, it might be a good idea to have it repeated in a few weeks, in case you are labelled incorrectly as "antibody-positive". There are sometimes 'false positives' that can result in a positive test. In any case, it is unlikely that you will have problems from it in the future, especially if you stay away from cigarrettes, tobacco etc!
Good luck
I am a 38 year old male with a 25 year history of migraine, sometimes severe. I have recently had a very similar problem to that described which i am currently having investigated now. It seems a major recurrence of something that happened 5 years ago.
Current medication:
Sodium Valproate - Migraine prophylaxis
Dichlofenac Sodium 75mg SR
Sumatriptan as required
The current episode began about 3 weeks ago. After feeling tired and sleeping one afternoon i awoke to find i had no feeling in my right arm. Tingling began and eventually it returned to normal after about 4 hours.
The following evening I had tingling in my left arm, foot and face. This extended to the left side of my tongue and across my scalp as a tingling sensation. When coming out of sleep the tingling tends to turn to numbness. I do have pain in my upper neck from time to time. It is mainly left side however I do have some right arm and foot tingling.
This has continued on and off for 3 weeks. Sometimes the tingling turns into a dull ache in the legs and sometimes it goes completely.
Reflexes are normal and I have no problem walking. Migraines have been virtually non existent since this started but i have had 'shooting pains' in my head which go off very quickly. Blood tests show a slightly increased inflammatory marker but otherwise are normal.
Going back to December 2004, I had the scalp and left arm tingling then and severe neck pain. I received osteopathic treatment as well as a long term course of diclofenac sodium 75 SR which totally resolved the neck problem and reduced my migraines massively. Due to stomach pain on the doctors advice I reduced the daily dosage of dichlofenac to 75mg/2days about a week before the onset of the latest symptoms. Although I have now returned to 75mg/day plus a stomach acid regulator this has not fully resolved the problem.
Again, going back about 5 years I had severe pain in the left part of my head and face which affected my vision. Initially concerned that this was trigeminal neuralgia i was prescribed steroid treatment and visited the eye hospital for vision tests. Field issues were evident at the time but cleared on a later examination.
Neurological examination and MRI were normal. Symptoms lasted 2 weeks and then cleared. The episode was put down to a complex migraine and did not return until now.
Any help or advice you can give is much appreciated. I will be seeing my GP again today and am asking to be referred to a neurologist.
