Hi I am 41 years old. I exercise regularly. My resting heart rate is 50bpm. I am 5ft 7inches tall. weigh 65 kg. After 35 minute training session on a bike yesterday I felt a sharp pain in lower left abdomen. has continued today but only seems to happen when I am seated or adjust my position when seated. Localised pain above left hip to the left of abdomenal muscle. It is only a fleeting sharp pain but wondered if it is something I should get checked out. I eat a diet of steamed white fish with steamed brocoli and new potatoes every day. Lunch is rice and tuna, every day too. I dont drink alcohol during the week but do enjoy a glass of red, or two on a weekend. I use a heart rate monitor during exercise and noticed yesterday my resting heart rate was 39bpm. normally around the 50bpm mark but dropped to 45 last week. not sure if that is relevant but thought I would mention it. Many thanks David

Hi David. Thanks for your query. Read the history and understood your problem. Sharp pain in the left lower abdomen, more so if in seated position or on adjustment of position in the chair, localized pain above the left hip to left abdominal muscles indicates that you should get this checked by a Doctor, preferably a Surgeon. Such type of pain can be a local problem of the muscles or a compression of the spinal cord by disc and causing the neurological referred pain. I would advise you the following:Examination by a Surgeon MRI of the spineOpinion of a PhysiotherapistFurther treatment as per the clinical examination and the reports. The cardiac problem, slow heart beats must be checked by the Cardiologist and investigated further for opinion and treatment,
