Levoxyl and mild flu

I was prescribed 25 MCG tabs of levothyroxine (generic for Levoxyl) by my MD for my hypothyroid. (I was tested at a 4.5 reading -- just below a normal 5 reading). After 60 days of taking levothyroxine EXACTLY as prescribed (i.e.; on an empty stomach, 1st thing in the morning with a glass of water; no vitamins for at least 4 hrs afterward), I started to have symptoms that I've never experienced before: my hands began hurting so bad with joint pain; my lips felt numb; and I was sweating more than I ever had in my life. I decided to stop taking the medication due to these symptoms, and in about 7-10 days from stopping, ALL these symptoms had disappeared and have not returned to date. I relayed this information to my MD who told me that my symptoms had nothing to do with Levothyroxine and that I needed to continue taking the drug. It's more than strange to me how some MDs will not listen to his/her patient -- even more so now that I've read other info on the internet where many other people have had these same side effects taking levothyroxine!! On my own, I am now looking into taking an all natural alternative that I found on wellness resources called "Thyroid helper". I will not take Levothyroxine again if I can avoid it by taking an alternative. Has anyone else out there had success taking "Thyroid Helper"?
