Hi, Thank you for posting your query in Health Care Magic, i understand your concern. The back ache which you are complaining about is most likely due to the spine problem. By your history i assume that when they say that your spine is not straight , you might be having a condition called as scoliosis (mild to moderate) and the pain might be due to the bent spine. But its really helpful if you can give me complete details of your liver and intestine problems as you have mentioned. That ways its easier for us to rule out the possible causes in your case. If the pain is getting relieved while taking tablets and then recurring it might have some underlying deformity. Get a Xray done of the lower spine as well as the cervical spine and do consult a orthopedician with the results . He will be able to assess and evaluate you better. Meanwhile reduce stress, straining yourself by excess work load, or heavy exercises. A course of physiotherapy will bring you a lot of relief and you could sleep on a flat surface for reducing the pain.. Hope this helps and answers your query satisfactorily . Do write back to us if you need further assistance, Wishing you good health . Take care, Regards.
