<s>[INST] I have a twing in my right side at the bottom of my rib cage.  It is sore to the touch but there isnt a bruise.  I also have slight annoying pain in my upper left thigh.  Sometimes the pain moves into my groin area.  Im a 51 year old female, light smoker, about 40 pounds overweight. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more. But since you are smoker, we should also rule of pulmonary causes. So get done chest x-ray and PFT (Pulmonary Function Test). If both these are normal then no need to worry about Pulmonary diseases. Your pain is mostly due to musculoskeletal cause. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Lose weight and stay healthy and fit. Avoid bad postures in sleep. Take painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected areas. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
