Pain in arm a week after blood drawn. Is this normal?

No: Not really normal, but also not unusual. It is often from a phlebitis, which is an inflammation of the vein the blood was drawn from. Warm compresses and NSAIDs can help. If it does not get better, be seen. ...Read more

I had blood drawn in same spot 3 times in 2 weeks. Arm is achey a few days after last draw. Shooting pain up from draw sight. Looks normal. Bloodclot?

Pain in arm after: In sticking in the needle the person who did it possibly damaged some underlying structures or caused some blood to leak and the leak, even though small, may be compressing some underlying structures. If you do need further draws soon, tell the person to draw it on the other side or from a different site. And talk to your doc about it today! ...Read more

High blood pressure: We declare hypertension (high blood pressure) if systolic (top) greater than 140 or diastolic (bottom) greater than 90 two or more times. So purchase a blood pressure cuff & track your BP at home after resting at least 5min each time. Then share record & cuff w/your doc. Tingling in hands could be carpal tunnel syndrome. Many reasons for fatigue. Discuss results w/your Family Doc. ...Read more

Shaky left upper arm and twitches after lifting weights for almost 5 weeks.Neuro exam,blood test and emg clean.What happened?Should I stop exercising?

Shaky left upper arm and twitches after lifting weights for almost 5 weeks.Neuro exam,blood test and emg clean.What happened?Should I stop exercising?

Neuro exam?: It is hard to estimate the degree of neurologic assessment that was done, particularly in the context of what testing was performed. Getting another opinion may be helpful here to re-evaluate any specific areas of weakness, correlated with subtle sensory loss and thus where nerve conduction and EMG studies could be (additionally) focused, especially if you were evaluated early in your symptoms. ...Read more

Foot pain for past 1.5 years. Foot tingling started couple months ago. EMG & Nerve conduction done results came back normal. How accurate are the test?

Generally accurate.: These tests are generally pretty accurate however this accuracy depends on the equipment and the skill of the person performing the tests. It is important to remember that even though the test results may show the nerves to have normal function, it is entirely possible to still feel pain. ...Read more

Abdominal pain after eating on left side, hurts to release after pressing down, nausea, diarrhea, shaking. Blood count & urine test came back normal?

Abdominal pain after eating on left side, hurts to release after pressing down, nausea, diarrhea, shaking. Blood count & urine test came back normal?

GI evaluation: This needs further investigation. May well be diverticular disease, but without more history and the ability to examine you and see all the lab data it is impossible to know what is going on. Follow your doctor's evaluation and advice and I hope this clears up soon. ...Read more

Thick blood , high inflammation levels abnormal liver function in all 3 blood tests, test back pos for blood clot on lung after dye test, back neg?

Thick blood , high inflammation levels  abnormal liver function in all 3 blood tests, test  back pos for blood clot on lung after dye test, back neg?

This is serious: I trust the dye test was a pulmonary angiogram that demonstrated a pulmonary thromboembolus, and it has also been determined that you have hypercoagulable blood. This is a major problem that will require work with your primary care physician and probably long-term medical management -- more than healthtap can do. Hope you do not smoke. The "inflammation" & liver labs need to be addressed in time. ...Read more

Tingling sensation then blood in urine. Passed sac 4 weeks later with white tissue. Took hCG blood test 3 weeks after was neg. Did I miscarry?

Tingling sensation then blood in urine. Passed sac 4 weeks later with white tissue. Took hCG blood test 3 weeks after was neg. Did I miscarry?

Unknown: Blood in urine is not a sign of pregnancy. I assume you passed tissue you're calling a sac vaginally, and not in your urine. Did you have a positive pregnancy test BEFORE all of this happened? If yes, you probably did miscarry. If NO, then there is no way to tell. You don't mention if you had normal periods; this information could help. Regardless, you are not pregnant now. Good luck! ...Read more

Would having recently donated blood result in low iron on blood test about two weeks later? Was also menstruating when blood was drawn for testing.

Would having recently donated blood result in low iron on blood test about two weeks later? Was also menstruating when blood was drawn for testing.

Potentially, yes: Unless you donate blood regularly this would be unusual, but if you couple donating blood with significant chronic blood loss due to menstruation, then this might be the proverbial "last straw". The good news is iron is easy to replace. It's best to do that with the supervision of a doctor to avoid overload. See what your primary care doc has to say on this topic. Thank you for giving blood=life! ...Read more

Are light periods a sign of pregnancy? Blood stays inside vagina. Happening last 3 months. Got 10 negative hpt and blood test

Are light periods a sign of pregnancy? Blood stays inside vagina. Happening last 3 months. Got 10 negative hpt and blood test

Tests are accurate: Pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) or 1 week after missing a period. If done correctly, a negative test result means not pregnant regardless of vaginal spotting or "light periods". ...Read more

I had stroke blood clot week ago , I feel shakey ,blurry vision  weakness ,is this to be expected ,?

Ask your neurologist: I'm sorry to hear about your stroke, I hope you are recovering well. If you are having new symptoms, you should tell the neurologist who treated you last week, as you might need to be examined to see if you had another stroke or progression of your stroke. Keep on working with physical and occupational therapy, the best time for hard work and recovery is the first 3-6 months! ...Read more
