Hello from JustAnswer. This is Dr. Love.
Whether you can wait until the morning depends upon how things go over the next 10-15 minutes. The threshold above which the blood pressure is worrisome is 180/110, and if either number is ***** this threshold, it should be addressed immediately.
The first step to address the elevated blood pressure is to see if resting for 10-15 minutes can help to lower the blood pressure below the threshold. If the blood pressure gets below 180/110, then it would be fine to wait until the morning. However, if the blood pressure remains above 180/110, then it is recommended that you should be seen emergently.
It is also fine to try to address any conditions that may be increasing the blood pressure during the period of rest. And particularly, in this situation, pain is a common reason for someone's blood pressure to increase. If you are having a headache or other pain, it is reasonable to take something for the headache/pain when you are resting. If you are having headache or pain and have already taken the dose of diclofenac for tonight, it is fine to augment the diclofenac with some acetaminophen.
So, if the blood pressure gets below the threshold with rest and pain medicine, then it is fine to wait until tomorrow, but if the blood pressure remains above 180/110, then you should not wait.
If I can provide any additional information, please let me know.
