My husband was diagnosed with shingles, is on antibiotics, but is in excruciating pain. Aleeve doesn't seem to help. What to do?

Are you sure. We do not use antibiotics for shingles. We use antiviral medications such as acyclovir, valcyclovir, etc and often use higher does of medications such as Naproxen 500 mg or Motrin 800 mg. Sometimes topical anesthetics such as a Lidocaine patch are used.
Many options. Shingle pain is nerve related pain, aleeve does not work. Narcotics may help. Also try gabapentin, tcas, ssris, lyrica, (pregabalin) they help too.
