Hydrochlorothiazide and blood tests

this medicin is killing me, ive had to apply for ssid dissability because of side affects of maxzide hctz i have comlain from start of this medicin ,problem is i guess that all blood tests come back normal for electrolites except once my magnesium was low but dr said it was no big deal and for me to just add a banana to my daily diet well that dident work and i only take a half tab of hctz everyday .i have no quality of life at all anymore because of cronic headachs and my whole body hurts ,all joints ,wrists feel broken knees too, muscles hurt and are weakening more everyday my muscles have what i describe as seazure type spasums , and now i cant hardly walk to my car cause my legs tire so fast, arms have same problem . and also i developed a cronic sinuse problem i can breath through nose but im allways feels stuffed up and overly dry .another problem for me is that i cant take ANY other bp meds do to alergic reactions and even worse side affects. i dont have insurance anymore .
