<s>[INST] I started have an aching pain in my left lower abdomen radiating to my lower rib area and sometimes my chest (under my left arm pit). This has gone on for about 2 weeks. Yesterday the pain started radiating to my inner left thigh and behind my knee. The pain is more intense when I walk, almost like a bruised feeling. I have been very tired and most of my joints feel very achy . Any ideas?? [/INST] Hi.Thanks for your query.Read the history and understood your problem.You have combined symptoms which look unrelated but if considered together  namely the pain in the left lower abdomen radiating to the lower rib area, chest, arm pit, for 2 weeks and now radiation to the inner left thigh and left knee back, it can be due to spinal problem .I would advise you to have the following:Consult a General Surgeon for a very typical presentation, clinical evaluation and physical examination to decide whether these are different problems or sue to a single problem having varied presentation. This will help to get the investigations done:The first should be EKG as you have chest and armpit pain. rule out the cardiac problem first. MRI of the whole spine from the cervical to the lumbar spineCT scan of the abdomen investigations of the blood, urine and stool. The final diagnosis hence made will help to formulate the proper treatment. </s>
