Hydrochlorothiazide and dry mouth

I have obly been taking the drug for a week but I am experiencing muscle weakness in my arms,vaginal itch and dryness, loss of sexual appetite and dry mouth

I have been on hydrochlorothiazide for about a year now, 25mg. daily. In the last 6 months I have noticed that I have very dry mouth in the evening especially, with a feeling that I have post nasal drip. It feels like mucus is between my nose and throat and there is no way I can swallow it...it never seems to go down. I have it until I go to bed, then it seems to disappear until the next evening. My nose is clear though. I also notice I am more jittery than usual during the day, and I have very sleepless nights. I seem to toss and turn all night long and don't feel rested in the morning. I am 66 years old.

Since I have been on the medication I have exsperienced red puffy hands that are VERY swollen. I have a lot of pain in my joints, including my shoulders. I hurt everywhere. I've also exsperienced extreme fatigue, dry mouth, sores on my tongue, a dry cough, and hair loss. Just yesterday I developed a rash the size and what looks like a misquitoe bite.
