Amoxicillin and headache

I started on a 10-day course six days ago for chronic sinus infection. Strange things started happening but I didn't connect it to the drug at first... first night, I kept waking up and having weird nightmares, very unusual for me. On the second day a headache from hell kicked in and lasted about two days. This was really awful, just bearable, but I still didn't connect it to the amox until a friend sent me the link to this page. It helped to know what was going on because the doc told me NOTHING, which really ticks me off. I've also been feeling very, very down and hopeless, also not like me, and the last couple of days I've had strange aches and pains all over my body. These feel like they're deep inside and unlike anything I've ever experienced. I'm a male in my 50's and generally avoid drugs and chemicals of all kinds. This just reminds me of what's wrong with doctors... all they know how to do is prescribe drugs and operate. Forgot to mention the constipation followed by diarrhea on the second and third days. Ugh.

Have had the flu for 6 days, taking 500 mg 3 times a day for accompanying bacterial infection on the chest. I had 40º temperature for the first four days felt awful due to that but now on reflection I believe the amoxicillin is causing mood problems; feeling furious about insignificant things, crying triggered by sad news stories (I am a man) waves of hopelessness and depression, today I sat in the kitchen and wept feeling pessimistic and overwhelmed by life.

The first 2 days that I felt ill I had no negative mood, just fever and headache, before I started taking the antibiotic. Also I think the first dose caused me to vomit.

sinus infection: 500mgx2 a day, on 7th day feel a lot better, but have also experienced a lot of side effects like others, worse for me is dizziness and fuzzy mind, want to sleep more, not a headache, just not feeling normal light headed as if i could pass out at times! obviously strong stuff!

Severe mood swings, headache, and fatigue!!!

I feel nauseous have a sickly headache, feel tires and I have developed very bad floaters in my right eye!
I am taking the drugs as a precaution as I have had pains in my head surrounding my cochlear implant site. I have had my cochlear implant eleven years with no problems but I have developed very bad stabbing pains in my head. I am hoping that the Amoxicillin will clear the pains albeit the nasty side effects.

Headache so terrible that I was ready to put my head into the oven. It kept me awake all night and improved slightly the following morning after I took a tablet of solpadeine. Never before have I experienced such a debilitating headache.

Taking a ten day course of 3 pills of 500MG per day. I had insomnia the first couple of nights. Some stomach problems and diarrhea. It is now the fourth day and I've been incredibly depressed and experiencing feelings of apathy and lethargy all day. Mood swings throughout the week; uncharacteristic short temper; general feelings of unhappiness or uneasiness.

Also, severe headache that lasted for the second and third days - hurt so much it woke me up several times throughout the night.

I was given 500mg Capsule of Amoxicillin for sinus infection. After 4 days on this med I am now getting all over body aches and pains. Not sure if this is a side effect of Amoxicillin or from the sinus infection. Either way I feel like hell. The Dr ruled out anything else, but I have chest congestion and headache and nasal congestion as well. It has abated some but taking a long time to clear up.
