Thank you doctor for the reply,
I have had terrible back pain for over seven years, especially while sitting or standing in one position. Recently, it has been to the point where I am unable to get up from the bed or toilet. Additionally, my knees often hurt while standing, and I have body soreness when I wake up in the morning. However, I do not have any obvious swelling. I also experience pain in my heels and wrists, and I randomly get shock sensations in my wrists. I experience dryness of mouth and tongue irritation, especially with acidic foods. I also have a rash on my tongue that is typically red with a white border. My eyes are often dry, but I wear contact lenses which sometimes makes it worse. I do not experience abdominal pain, nausea, or vomiting, but I usually have diarrhea and bladder issues. Sometimes, I feel a strong urge to urinate, but when I go to the toilet, I have difficulty passing urine.
