Thanks for your question on Healthcare Magic.
I can understand your concern.
You had
blunt trauma due to fall.
Your current symptoms are mostly due to that fall.
Yoi might have injured back (muscles, vertebra and
spinal cord) and abdomen by that fall.
So better to
consult doctor and get done clinical examination,
ultrasound examination of abdomen and x ray of lumbosecral spine to rule out injury.
If all these are normal then possibility of simple musculoskeletal injury is more.
So apply warm water pad on affected areas. Avoid movements causing pain. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Take painkiller and
muscle relaxant drug.
Don't worry, you will be alright with all these but first rule out internal injury.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
