Lately I have been feeling fatigued, cold syptoms, extreme aches- like when I had mono, pressure in abdomen after intercourse, lower back aches.

I'm worrried! Please help!

I am so sorry you are feeling ill and worried. Best advice is to visit your doctor. You might ask them to do a Urinalysis to check for bladder infection. That can cause lower back pain, fatigue, aches, leg aches, even could be causing the feeling of pressure after intercourse, etc. Some bladder infections cause extreme pain on emptying your bladder but others don't for awhile so it can be confusing.

If you have had mono, you might ask your doctor about Epstein Barr Virus. It is like having chronic mono. The symptoms are so numerous, no definitive tests and some doctors do not recognize it but I had it in 1985 and was in bed for almost a year. Doctors kept telling me nothing was wrong because they checked for lupus, leukemia, soft tissue diseases, etc. and found nothing. A specialist diagonosed me finally and I received information that really helped.

Are you running a low grade temp?

So many things these symptoms could be stemming from... as I said, best advice is to go see your doctor or gynecologist. Please don't put it off. It could be something minor that could be cleared up with one round of antibiotics. Sure would relieve your mind I am sure. I don't like to go to the doctor and I know you probably don't want to either but best to relieve your mind and the sooner the better. Praying Good Health for you!
