I was about 1 month in to my 3 month cycle of taking doxycycline for blepharitis issues when I started having symptoms. It started on a friday night with extreme indigestion. There was a lot of pain in my chest and also into my arm. I was belching and very uncomfortable. Next day I woke up and only had the pain in my arm, belching and pain in my left abdomen under my rib cage. I thought it was just really bad indigestion from something I ate so I continued with the medicine. Within a few days time I deteriorated more and more. The pain in my abdomen had spread from just being on the left to being left, center and right. I also got random pains all over my body it seemed. This seemed to come and go throughout the day. My vision would blur, I had extreme anxiety and also depression, my arm remained weak and then my legs got weak as well. The fatigue was overwhelming. I'm usually an insomniac who struggles to fall asleep by 1:30. I began to struggle to stay awake until 11. The lymph node in my neck also enlarged, and I began to experience a loss of appetite. I have currently lost 5 pounds in one week. I also always feel dehydrated and in a fog. I went to an urgent care clinic and the doctor really just thought I was crazy from what I could tell. I stopped taking doxycycline about 5 days ago and the fatigue is slowly letting go(very slowly). The blurred vision has cleared up a bit but still comes and goes. My mood is still very down and I can't help to still feel anxious and can't stop wondering if I have some deadly disease process going on. The heartburn and abdomen pains are also subsiding slowly(I feel a little better each day). I'm glad I found this website. It's helped me not freak out as much about my symptoms(although I still have my moments). Since I started feeling bad I've convinced myself that I have heart attack symptoms, pulmonary embolism symptoms, symptoms of AIDS and symptoms of lymphoma. It's still hard to not feel like doomsday is upon me but reading that many of you have had similar feelings and side effects makes me feel a little better. I just hope this clears up soon because I think as long as I feel pain, tired or anything off I will be anxious about it. I have fear of ending up on Mystery Diagnosis lol.
