My lower legs, feet, knees have moderate pain daily. I also suffer from being tired, fatigue, abdominal pain. Went to a Care Now 6 months ago and was prescribed anti-inflammatory drugs. My blood came back slightly elevated, dr was not concerned. This pain has been increasing for the past year and half. I consider myself to be healthy and active on days I can walk.
Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have severe knee pain, fatigue, lower leg pain and abdominal pain. Well there can be many reasons for symptoms you mention in query mononucleosis, Lyme disease, sinusitis, diabetes, type 2, rheumatoid arthritis or multiple sclerosis. I would suggest you to consult orthopedic surgeon for proper examination. Doctor may order certain test like MRI of knees, check for hernia, sciatic and order blood test. Doctor may also refer you to gastroenterologist for gastric problem or ENT specialist for sinusitis like problem. For now take ibuprofen or acetaminophen for pain, Chat Doctor.  Hope your concern has been resolved. Get Well Soon. Best Wishes,
