I had a bad dose of flu March/April which badly affected my thyroid medication dosage. I had been on 150mg Levo for 25 years with no problems, then 'boom', I started to experience all the symptoms of overmedication/overactive thyroid: crippling anxiety, inability to concentrate, headache, twitching muscles, inability to sleep. It took a while for the GP to figure out this wasn't just the flu. On 13 May dropped to 125mg Levo - anxiety/agitation declined but developed excessive urination, abdominal pains with sleeplessness. 29 May dropped to 100mg - gradually excessive urination reduced and sleep improved but started to develop pins and needles and numbness in feet and hands. 11 June dropped to 75mg Levo - pins and needles and numbness declined, twitching much reduced but feeling pretty washed out! Each drop in medication has reduced or eradicated symptoms but now I'm waiting until August before we can test levels again. I'm 49, male, 13 and half stone.
In retrospect I feel like I was possibly going hyper prior to the illness: I had made some major lifestyle changes (giving up alcohol, much less sporting activity). When I had the flu I made several changes that may have inadvertently raised the levels of medication in my system? I started taking my Levo properly (empty stomach, hour before food) completely cut out caffeine and radically improved my diet. Has anyone else experienced similar effect as a result of flu?
I'm seeing my GP later this week + testing lots of other stuff (B12, Folate, parathyroid, prostate). I also want them to look at the full range of vitamins. GP is saying they might refer me to a neurologist because of the twitching (which has reduced considerably due to the dropped dose).
Should I talk to the GP about adrenal insufficiency/recovery?
Will my thyroxine levels drop steadily over the six weeks while I'm waiting to test? Or do they take a couple of weeks and then the rest of the body has to adjust?
