My Husband Has Been To The E.R. Three Times In

My husband has been to the E.R. three times in the past five days. Five days ago, and for the first time in two years, he took one FLOMAX tab and within two hours had a migraine, body aches, chills and fever. Yesterday, he had an MRI to rule out ITA, Stroke, meningitis, etc. The scan was clear. Today, he awoke to swollen eyelids, yellow skin on the inside corners of his eyes, and his fever has climbed to 101.2 (armpit). I am calling the very few neurologists we have in Southeast Idaho, but I am wondering if this the answer. E.R. cannot help his pain because he cannot take the usual pain meds without 'climbing the walls'. He cannot take antihistamines because it further aggravates his prostate. He is currently taking a different anti-nausea med, prochlorperazine and for pain: Tylenol, Tramadol, and a different pain med- Meloxicam. The headache remains, the fever remains. Thank you for any help.
