The symptoms as mentioned in your post can be due to:
or injury to back muscles
2. Referred pain
due to any cause in the gastrointestinal tract e.g. Peptic ulcer
3. Pathology in the Respiratory system e.g. Pleural effusion
Aggravation of pain on sneezing
can be attributed to increase in intra-thoracic pressure.
Investigations like X ray chest & Ultrasound
scan of the abdomen will be helpful to detect any pathology in the Respiratory system & the Gastrointestinal tract respectively.
Based on the findings, appropriate management steps could be taken.
