Inhalator symptoms and conditions

Started taking Levothyroxine 100 3 weeks ago, for last week I'm in agony, my joints and muscles are sore, specially legs and arms, got constant headaches, mood swings, I'm also short of breath which developed before muscle pains, went to the doctor, was told it's probably asthma (!!) got tablets and inhalator and he mentioned anxiety, when muscle pains started, went back, was told that it's not related with hypothyroidism or Levothyroxine, it's a virus (??) have to drink plenty of water and got Diazepam and link to anxiety website. Help, it's not stress related! I don't know what to do!! Does anyone know how to get rid of those pains?

I am a 57 year old man, who has been suffering from asthma several years. This spring my doctor put me on Singulair as an additional medicine to my cortisone-inhalator. after one month I feel symptoms of depression an mood-changing, severe ups and downs.
AND - as an additional symptom i have partially lost my feeling in some fingertips, and now parts of my left thumb and even a feeling of "cold2, mostly in my left hand.
anyone who share that symptom?

I am a 56 year old man who has been suffering of asthma for several years. This spring my doctor put me on Singulair as an additional medicine to my cortisone-inhalator. After one month I have the same experience as many here has told about - depression and periods of "swinging mood", ups and drastical downs.
AND - a growing problem with feeling in my fingertips, seem that with accelerating speed i am loosing feeling in fingertips and now even the hold fingers and parts of my hand, which feels "cold".
Anyone here who recognize these symptoms?
