32 yrs old, in december hurt my back i was lifiting,i sprained my back, went to the dr.said i did not have anything wrong. so i was sent home with pain killers and that was that. then in january i had this itch on the side of my stomach i was not sure what it was then the 2nd day of the itch i noticed i had these red bumps on my left side of my rib area. i was for sure it was a spider bite just because it was red and was tender and itched really bad. and where red bumps were at i had numbness like around the bite but like almost my whole side of my left stomach. anyhow i go to dr they said it was ring worm. which i thought was werid cuz it did not look like ring worm. ok now this month i get these welts or hives not sure what they called. dr says allergic reaction maybe to something i ate, i get a shot of bendrly, then next day i get another shot because i still had them. then after 2 days of them. i was having bad headaches, and nausea, for about a week. then i after i notice i was gettin a warm sensation on my left lower leg. it will come then go. then the other night i noticed it got a cold feeling for a few minutes. but usually it gets warm. i just scared it is a blood colt? i have apt on mar 5 for dr. but i am really scared, i do get colds a lot, but thats about it. when i went to the dr, i told them about the numbness in my left leg. he said nonthing about it.its a non profit clinic i dont have insurance and scared, i had to ask the dr if i can get a test for diabetes and hyperthyroidsm, i had to ask him for it. and he tells me come back in a week which is the 5 of march. im loosing sleep over this. i forgot to metion when i got the welts i was stressing a lot for my dad, he had an eposode of dementia and i was worried for him. not sure if its stress or what. can some one give me advice please.
