Hello, I am a 55 year old female, I have itchy skin, feel exhausted, my muscles ache, I don t sleep well, I feel depressed and anxious a lot, I recently had a lump in my left breast and the doctor thought it was an infection of sorts and put me on antibiotics, I didn t finish them all as I was having a sick stomach from them and noticed that some sinus stuff and sneezing seemed to also subside when I was taking the antibiotics. I am overall exhausted feeling....the lump went away from the antibiotics, ears are constantly plugged, post nasal drip a lot. Wonder about vitamin B deficiency and maybe D?
