Worried about my lymph nodes, can anyone help?

Thats totally normal and reallyis nothing to worry about. Lymph glands get enlarged all the time you just have never noticed them before. When you have had an infection the lymphatic system works to mop up all the dead and dying cells which is why they become enlarged and hard. Lymph doesnt pump like blood does so it takes a while for them to empty again. The one under your arm is linked toyour ear infection also. If the ear infection is stubborn then it might be a good idea to do a search and look at candida albicans and see if the description fits you. Yeast overgrowths often lead to ear infections. After taking the antibiotics make sure you take a coupleof sources of probiotic supplments. Make sure you get one that is guaranteed to deliver live bacteria so that you restore the probiotics in your digestive tract which will have been killed by the antiobiotics.
