My husband's back started bothering him about 2 weeks ago. Severe pain, does not know what he did to it. We have a sleep number bed and I lowered the number and that seemed to be helping. Yesterday his mouth started hurting, woke up this morning and the whole side of his face was swollen. He went to a walk in clinic and they prescribed amoxicillin. When he was sitting on the couch, he kind of bent forward and now he can barely move. Now he's shaking from being so cold. Are the 2 related?
