<s>[INST] I am 56 years old. take meds for fibromyalgia, degenerative disc disease and anxiety. I was driving my car for a few hours. When I stood up, my legs were swollen, shins were hard to the touch and a thin line around my ankles cracked open. I stopped driving for the day and rested. The next day, my neck glands hurt somewhat but not severe, but my tongue turned purple blue with lesions. I drank only water, oatmeal and slept a lot. No fever, but slept. was too tired to drive to the dr. and wasn t sick enough for an ambulance. Also the 2nd night no fever, but felt hot/cold/chills all night.I did have a pain in m lower back, but I contributed it to the degenerative disc disease. I never saw a tongue turn that color. After a week the color became less bright and the lesions left.Still curious. That week I had traveled to NY and was seen by a few physicians including an md. [/INST] Hi, In fibromyalgia, by definition, nothing is wrong. And, in this case, something was wrong without an exam, I can only give general information. Sudden swelling in ankles with a component of circulatory problems is generally considered blood clots until it is ruled out because they can go to the lung and cause hypoxia with blueness. I'm sure it's just a coincidence though and other issues like infections, autoimmune diseases, or mild viruses can cause some of the same symptoms. Hope I have answered your query. Let me know if I can assist you further.  </s>
