I started having a cough two weeks ago. It started affecting my sinuses about a week ago, so I started taking cold medicine. Instead of getting better, it just got worse. Three days later I would blow my nose and get green-yellow mucous. The next day I woke up and hurt from the crown of my head and down the left side of my head in my ear, jaw, neck, and shoulder. The pain was so bad it even hurt to eat. This is by far the worse sinus infection I have ever had! So, I went to the doctor. He prescribed an antibiotic and an antihistimine (my blood pressure was slightly up, which could have been because of the cold medicine, but it caused him to not want to give me a decongestant). i'm still hurting in my head, ear, and jaw, but not as bad. Mucous is still very colored. But, yesterday, I started hurting in my right shoulder--more like on the tip of the collarbone near my neck. It has some sharp pains, and sometimes dull and achy. I haven't done anything physically that would have caused this type of pain. It doesn't go into the shoulder itself, it just feels like it is in that collarbone. It does hurt also when I move it some and when I cough. Is there any way that this pain could be connected to a sinus infection or even to antibiotics? I'm just wondering because I really have no other explanation to the pain--if this is even an explanation.
