Greetings doctor, for the past 3 months I ve been having muscle spasms, tingling, numbness, weakness, sensations of pins and needles all over my body, mostly in my arms and legs, I ve had difficulty breathing, and two panic attacks. Sometimes I can hardly walk, when I walk down stairs my legs hurt, recently I ve become stiff and my joints have been cracking a lot,(knuckles, fingers, toes, shoulders, knees, neck, back) I ve had a history of back and neck pain and also I ve had bowel trouble for about 3 years, I m a male and 19 years of age, I live in south america and I ve seen a doctor and have had many blood tests those of which all returned normal, ct scan normal, cat scan normal, only thing abnormal that was discovered was that my muscle enzymes were high. Doctor Im praying that I m not a victim of ALS, I don t mind having anything else but I need someone to confirm that I m not an ALS victim. Please help me.
