My husband is a pretty healthy 48 year old who has worked construction his whole life This past year he has been suffering some very odd symptoms. The heat has become almost unbearable for him, resulting in sever muscle cramps, all over his body. This is more than run of the mill dehydration, and we have been to the ER several times because of it. He is also suddenly prone to muscle tears, which have never happened to him before, one in his leg, one in his bicep. He is VERY tired lately, more so than normal, and even when he isnt working hes exhausted after only being up a few hours. We have had his testosterone tested (slightly low) and been sent for routine bloodwork, but something is wrong and we have to get to the bottom of it What else can we suggest our doctors look for
