Question: I am 60 years of age with no known health issues. I was sitting at my desk and felt like a huge hit was delivered to my vision went tunnel and sideways and then black. I was not conscious but something inside me told me to count and I remembered I got to 9 and then my tunnel vision appeared and then went away with my head down on the desk (I was sitting so I only collapsed onto the desk). No apparent symptoms of stroke that they tell one to check for.

Brief Answer:
Presyncope most likely.

Detailed Answer:
Thanks for your query!

Hi most likely it was presyncope. Presyncope is a state of lightheadedness, muscular weakness, blurred vision, and feeling faint Presyncope is most often cardiovascular in etiology.

I would suggest you to go for few baseline tests for cardiology like
+ Stress test-A cardiac stress test measures a heart's ability to respond to external stress any ischemia is suggested by ST-T changes on monitor.
+ 2d echo-Motion of wall of heart and cardiac output is seen.Tread mill test and 2d echo are 80% sensitive to rule out cardiac diseases.

Other system which may be involved are-
Nervous system- Decreased supply of blood to brain due to clogged carotid artery.
+Carotid artery Doppler should be done to rule out if blood supply to brain is normal.
+Electrolyte imbalance-Serum electrolytes should be checked.

Tests advised
+Serum electrolyte
+Carotid artery Doppler
+2d echo
+Tread mill test.
+MRI brain stroke protocol.

So I have had some swelling for a few days now in my ankles. It goes through waves in term of pain and varies from tolerable pain to excruciating pain. The pain seems to come from my ankles and near my hips, making moving almost impossible. The past two days I have developed red lumps, the size of large mosquito bites. They did not hurt at first but today, they are hard and painful. I have not been outside or near anything that could contain bugs that could do harm and ultimately, bite me. I did recently come back from a visit to the midwest and back that was 10 hours each way. I have been to two doctors, in which they took blood and did an ultra sound but I have only received news from one doctor that my blood work is normal (Kidney, Liver, Glucose levels). They did indicate that I did have a slightly higher-then-usual blood pressure which may be an indicator or may be due to my stress and anxiety from this entire situation. I also have been having moments where my ears have been ringing along with lightheadedness. I don t know what it is but I am wondering if its allergy related. Any insight would be fantastic!

Hi, I am on my third day taking Duromine ( Phentermine ) 30mg and I have been experiencing some of the common symptoms associated with taking this eg headache , lightheadedness , dry mouth however I have had ZERO reduction in appetite! I am starving constantly and stopping myself from eating but I have massive hunger pains every 2 hours or so. I am drinking over 2litres of water a day but even this isn t keeping me full. I am currently menstrating and wondering whether this is why I am hungry? Could my appetite be increased because of this and this is why they are not working or should I go back to my gp to get a 40mg prescription? Everyone else on duromine has to force themselves to eat and even forget to eat because they have such little appetite and I m the complete opposite and starving! I m very confused!

I sometimes get a weird feeling in my head. I call it being light headed, but I read about light headedness and my feeling doesn t fit. It is like sinus pressure because it is in the sinuses as well as the top of my head. It doesn t happen all the time, but is annoying when it does.

I am a 43 year old male in good health and take no medication. Very occasionally I wake up in the middle of the night with a strong, dull pain in my anus. I have assumed it was hemorrhoids and have used Prep H in the past which took away the pain in 5-10 mins. However, the last 2 times I had the pain and applied the cream I immediately felt light headed, broke out in a cold sweat and noticed my heart rate was very, very slow. I have never passed out in my life but I think I was on the verge of doing so. My questions are what happened to me? Can pushing or application of Prep H to the inside of the anus upset things which causes the light headedness, cold sweat and decreased hear rate (low blood pressure??)? Is it actually hemorrhoids or someting worse? Thanks for your help.
