Hi This morning I had a client for a massage. David has been coming to me for yrs on a wkly basis. Lately I have noticed the lymph glands on each side of his penis, to be quite raised and painful. I advised him to see a doctor which he did. the results...high sugar levels. today I had to stop the massage 1/2h in as David got very light headed and nauseous. had 2 glasses of water before he left and since then (9.30am) has been drinking non stop. After just checking on him, 20 big glasses of water and can t stop drinking raised alarm bells in my head. is this normal?
