Do a saline nasal spray, keep it on U at all times & do several times a day. Drink lots of water, rest (I know, yeah rt-but try), drink orange juice, sleep w a humidifier I Ur room (really run it 24/7). Hope U feel better.
I had similar symptoms, but was diagnosed with an upper respiratory infection. I was out of work for a week not taking anything, just rest and fluids, but didn't start feeling better until my midwife told me it was safe to take Tylenol, Benadryl, and Sudafed (after the first trimester), the Sudafed is what finally gave me relief for work.
I was able to take mucinex dm, Tylenol, and benadryl when i had my sinus infection. Also, on claritin now. I would recommend going to the dr just to make sure that diagnosis is correct and to see what they recommend for you.
