Hi,
As you fell on your back and neck, little pain in those areas for few days is normal. As far as the pain is reducing in intensity and you can maintain your daily routine, there is nothing to worry about.
If you develop symptoms like
dizziness,
vomiting,
disorientation,
severe pain in back or neck, then I would advise you to visit a physician for physical examination of the injury, get x-rays and MRI done and rule out severe trauma to the vital parts of the body.
Your pain will subside automatically when the injury will heal completely. The wound or bruises are not seen from outside, but back, neck and head have absorbed the shock so they do need time to heal.
Meanwhile, you can take
Ibuprofen 400 mg or
Paracetamol 500 mg to alleviate pain as and when needed. These medicines are available easily over the counter. Take these medicines only if you are not allergic to them.
There are also many mild to severe causes that can cause headache other than injury to the area. If your eyesight have developed problem, you have migraines, your stomach feels upset, you have not had adequate sleep, you have developed
hypertension, then also you can feel headache. There are many other reasons that can contribute to headache. So if you do not feel any relief in pain in next 3-4 days, I would recommend to see a physician for physical examination and rule out the specific cause of the headache.
I hope this information helps. Thank you for choosing HealthCareMagic. I wish you feel better soon.
Best,
Dr. Viraj Shah
