Then the next.day i woke up and all my joints horribly also my hands and feet even the insides ache. this pain is random and i have not been working out or anything. my chest also has this se what painful pressure. i am so scared because pain is so bad and out of the blue. any ideas? please help [/INST] Hello, I think you need to get the blood and urine test done and meet up the orthopedist for the physical examination. Any pain in joints can be consulted with verbal form but then when you mentioned about the chest I think lab tests are needed and orthopedist examination too. Hope I have answered your query. Let me know if I can assist you further. Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist </s>
