Doxycycline Hyclate and fibromyalgia

I took Doxycycline in 98 for 3 months when traveling in SE Asia, I became extremely paranoid and my hair started falling out (I've never had this prior or since) so I stopped taking Doxycycline and within a few day's I was back to normal. Last year I went on another trip to SE Asia and was advised to have Doxycycline again with lots of assurances that it would be fine despite my previous reaction. After 1 week of having Doxycycline I awoke in the middle of the night with extreme pain running up and down one side of my body. Since then I have never been the same, constant reoccurring problems of the Central Nervous System including nausea, twitching, numbness, tingling, blurred vision. Also initially I had hair falling out. I've been tested for MS, fibromyalgia, lupus, lymes, etc. with negative results so far. The doctors dismiss the possibilities of a adverse reaction to Doxycycline but I'm not so sure. My reaction in 98 was very obvious to me if no doctors seem to think so. I had also had a vaccination for Japanese Encephalitis.

I began taking 100 mg x2 per day for ten days for a bacterial infection. I am 48 years old and I have Fibromyalgia and arthritis pain issues as well as other health problems. By day three of taking doxy, my pain issues increased dramatically. My legs burn and the pain the runs from the waist to the heels of my feet are not something that has happened to me before...thus, I surmize it is the doxy. My legs and feet burn and hurt so much that it is difficult to walk and to sleep as even resting them on the mattress keeps me awake at night. I tried taking it with a tbsp. of peanut butter and a small glass of milk and in 15 minutes I vomit. I need to have considerable food in my stomach and yet, I have great stomach pain that comes in waves. This is a very difficult medicine to take!
