Hello dear,

The symptoms as mentioned in your post can be due to:
1. Sinusitis
2. Tension headache
3. Migraine
4. Cluster headache

Management involves:
1. Paracetamol (500 mg to be taken thrice a day) for symptomatic relief.
2. Antibiotics based on culture & sensitivity reports.
3. Steam inhalation
4. Antihistamines like Allegra can also be used.

So, kindly consult your General Physician & start treatment.
Investigations like complete blood count & X ray of para-nasal sinus will be helpful.

Wishing a good health.
Take care.

Hi!
welcome to HCM!
Your husband seems to be suffering from sharp occipital headaches which can be due to Occipital neuralgia.It is a distinct type of headache characterized by piercing, pain in the upper neck, back of the head, and behind the ears, usually on one side of the head. Typically, the pain begins in the neck and then spreads upward. The location of pain is related to the areas supplied by the greater and lesser occipital nerves, which run from the area where the spinal column meets the neck, up to the scalp at the back of the head.

The pain is caused by irritation or injury to the nerves, which can be the result of trauma to the back of the head; pressure on the nerves by overly tight neck muscles; compression of the nerve, due to osteoarthritis, as it leaves the spine; or rarely tumors.

Localized inflammation or infection, gout, diabetes, blood vessel inflammation , and frequent lengthy periods of keeping the head in a downward and forward position are also associated with occipital neuralgia. In many cases, however, no cause can be found.
You must get him examined by a neurologist.
hope this helps!Take care!
