In one sentence, describe what the following article is about: If home treatments do not help your headache, see your doctor. She can rule out underlying conditions and formulate a treatment plan for you. Your physician will zero in on the correct diagnosis and exclude competing diagnoses in an attempt to pick the correct therapy. She will determine the need for additional testing at this appointment, which may include but is not limited to a blood pressure check, additional cardiovascular review, blood work, head imaging, and more. Depending on the severity and type of headache you have, your doctor may prescribe you a powerful pain reliever as well as a preventative medication to help stave off further headaches. Your doctor may give you prescription pain relievers including sumatriptan and zolmitriptan. Your doctor may give you preventative medications including metoprolol tartrate, propranolol, amitriptyline, divalproex sodium, and topiramate. Many of the preventative medications are especially effective on migraines because they counteract blood vessel constriction or the painful dilation stage. Some antidepressants may also help prevent extremely bad headaches. If you suffer from cluster headaches, oxygen therapy is considered to be one of the best treatments. You will inhale oxygen through a face mask, and your headache may be relieved in as little as 15 minutes. Oxygen therapy is most effective when used right at the start of a headache. You must resume treatment when another headache begins. There are other, more rare treatments you may want to discuss with your doctor. These include botox injections and transcranial magnetic stimulation. There are some studies showing that Botox, which is the Botulinum toxin type A, can help relieve and prevent bad headaches. Discuss this with your doctor should your headache not improve with standard therapy. Transcranial magnetic stimulation uses electric currents to stimulate nerve cells in the brain, which may help minimize the pain associated with headaches as well as their recurrence.
Summary: Consult your physician. Ingest prescription or preventative medications. Try oxygen therapy for cluster headaches. Consider other treatments.

In one sentence, describe what the following article is about: To ensure that you're purchasing pure tung oil, look for the words "100% tung oil" printed somewhere on the container's packaging. You can find tung oil at a local paint store or hardware store. 1 quart (0.95L) of tung oil or Waterlox will cover about 15 feet (4.6m) of butcher block. If you'd rather apply a longer-lasting product than tung oil, you can seal the butcher block using a more substantial chemical sealant, like Waterlox. Both products are food-safe. Dip a clean, dry cotton cloth or rag into the container of tung oil or Waterlox. Then use the cloth to rub the sealant across the surface of the stained butcher block. Work in long, straight strokes that parallel the direction of the boards in the butcher block. Give the sealant a full 12 hours to dry. Sealing the butcher block is a time-consuming process. It will need several layers of tung oil or Waterlox. Use the same method for each layer: saturate a clean rag with sealant and then rub it along the surface of the butcher block. Use a clean cloth to remove any excess sealant. Ensure that each layer has at least 12 hours to dry before applying the subsequent layer. Avoid using the counter for 7 full days so the oil has enough time to fully soak into the wood. Once the week has passed, you can use your stained butcher block counters. You can still use your butcher block countertops before a full week passes. However, they'll be oily and may stain your dishes or clothes. Tung oil wears off eventually, at which time it needs to be replaced. Every 4 monthsor as soon as the surface of the butcher block begins to look fadedapply a layer of tung oil to the wood. The additional coats of oil won't take a full week to dry. To be on the safe side, though, give each layer 3-4 days before using the countertops.
Summary: Purchase 100% tung oil from a local paint store. Apply a layer of tung oil to seal the stained butcher block. Apply 4 additional layers of tung oil to the butcher block. Give the tung oil a full week to dry. Put on a new layer of tung oil every 4 months.
