I'm spiralling so hoping for specialist recommendation. A month ago I was prescribed ciprofluoxcilin for a UTI. I took the antibiotic for 5 days. At the same time I was sent for blood tests due to signs of infertility. My GP called to say I have TSH 18 indicating underactive thyroid. I started on 50mg of levothyroxine and took a second blood test that showed extremely high antibodies suggesting hashimoto disease. My issue is I had no real symptoms of the thyroid issue other than the infertility. I have a stressful job and was tired but that's all. However, since taking the antibiotics I've been extremely unwell. Not able to work. I have fatigue, muscle pain, joint pain, debilitating headaches, which is causing me to also feel very depressed. My gp just says it's the thyroid and all my other results of the blood tests are normal (liver, kidneys, anemia) but it doesn't make sense for me to be so ill with no previous physical symptoms like this. There does seem to be other thyroid patients who have had issues with ciprofluoxcilin however which is worrying. I would like to speak to a specialist to try and get some answers and not be fobbed off with just rest and wait 6 weeks for your next blood test. Anyone else had similar experience? Got advice? Or could recommend specialist in the Kent or London area? Would really appreciate it!
