i have a 17year old daughter- who has mono for the 2nd time ..in addition to asthmatic bronchitis- she has been sick since before thanksgiving lost 11 lbs- her bronchitis has gotten better the last week- however now has severe sinusitis. i ve taken her to immunologist - as i am concerned about her immune system/ he ran blood test and allergy test- he said he wants to start her on allergy shots once her mono symptoms are better as he feels that will help her asthma i m concerned because before the mono in november - she has complained randomly - dizziness, she gets numbness in her arms and legs at times and on 3 occasions have had to sit down as she felt her legs will give out- she also has the shakes at times/ especially when she paints or does tedious things w/ her fingers or hands/ with all this info i m asking if its possible there is an underlying issue
