Hello,
Thanks for posting your query.
If the headache is due to vision problem try to correct it , since many a times it is the cause.
Also reading in dim light would also cause it so always read in places with adequate lighting.
Stress is another important cause so try to reduce your stress levels and if it is occasional you can use analgesics.
Regarding
hip pain, if you have history of trauma or fall remember and try with analgesics and your headache and hip pain would not be related to each other.
Also try with hot fomentation.
Hope I have answered your query.
Wishing you good health.
Regards,
