Possible diagnosis? i have the following symptoms but i dont know if they are related and what the problem is.

i have the following symptoms:
- Amenorrhea (missed period)
- multiple negative at home pregnancy tests
- no other symptoms of pregnancy (also have only had intercourse once since last period and a condom was used)
- lower right back pain that radiates down my thigh to just below my knee

other information...i am a 21 year old, white female, college student. stopped taking hormonal birth control 2-3months ago. i have been healthy, with the exception of about a month ago when i had a cold that presented with an painful, enlarged lymph node on the right of my neck that has since resolved itself. my family medical history is significant for weight related diabetes. i am not taking any drugs.

Get yourself to a doctor. The pain in the back, radiating down the thigh is suspiscious. Don't waste time writing questions here, go get help. Ask for a pap smear test.

did you watch house this evening?

Please go to a doctor, this could be very serious, it could be a number of things!

best advice i can give you is to go see your doctore and tell him all of your symptoms. ASAP good luck

sike! bet you got scared. who knows whats wrong with you. have any of you heard of a doctor?

often after a period of taking the OCP your normal cycle will take time to reset itself. You may have multiple periods or spotting - or nothing at all for a few months. If you are underweight this can also affect whether you have periods or not (you need a certain amount of fat stores in you body to produce enough oestrogen.

It is possible that you are just simply stressed out. You are a college student and you probably have alot on your mind too. As far as the pain goes, you might just need to go get your back straightend out. I wouldn't worry too much if I were you. I've heard of people missing their periods because they were just too stressed out.

Amenorrhea could be due to your body getting used to no more pill being ingested, especialy if you wer on it for some time prior to ceasing to have it.
Lower right back pain radiating, probably sciatica..need to see a physio or go swimming to correct this. Best see the phys though, as you could have put your back out, and the backbones are probably just compressing your sciatic nerve that runs through your but and down your leg. Usually happes when you go to get up and walk and you get the referral of pain and it stops you walking all together.

It's all in your head. Forget about it and you'll be fine.
