When i woke up this morning i had an awful stomach ache.. My lower abdomen was hurting very badly so i took some pain medication. Then, later in the day at the beach, I suddenly got a horrible headache that made my head sore to touch, and it was very sharp pains. Now i m laying down, but now i feel like i m going to vomit, and my head is still hurting very bad. What should i do?
