Thanks for your question on Healthcare Magic. I can understand your concern. No need to worry for major lung and intestinal diseases because your chest x ray and ultrasound abdomen are normal. Also don t worry about worm infection. Possibility of musculoskeletal pain is more likely. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Avoid sudden jerky movements and forward bending. Apply warm water pad on affected areas. Take simple painkiller like paracetamol or ibuprofen. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
