Symptoms began 14 months go with abdominal discomfort ,constipation and anxiety. Had UGI series, colonoscopy and gastrocopy...all negative. Have had regular blood wrk. I have thinning hair and I have developed an allergy to cold..swelling and redness of face and hands. A month ago I noticed that my hands tremble especially when using a fork or spoon. The past couple of weeks I have had cramping of my fingers .when walking any distance, such as when shopping, I get the feeling that my muscles are seizing up. I am also having memory problems. Your thoughts, please....Thanks!
