Hello. Thank you for posting your query at DoctorSpring.com
I understand your concern.
Thank you for your elaborative history. It is great to interact with patients who are so interactive and provide all the necessary details.
I went thorugh your blood reports. Adressing your concerns one by one,
There are several causes of light headedness. The first and the foremost cause is a slight drop in BP, which can happen due to postural changes, on sudden standing from sitting position, and at time the cause can be idiopathic ( no identifiable cause, but there is a drop in BP ). The other causes of sudden light-headedness can be anemia, a possible Coronary Artery Disease leading to heart-attack, stroke or TIA ( Transient Ischemic Attack ), associated with vertigo, alcohol intoxication, low blood sugar ( e.t.c ).
Since you have attached the blood test, anemia can be ruled out, and low blood sugar or elctrolyte imbalances can also be ruled out. The doctor did evaluate you for a possible heart attack, but you troponin was also in normal range. Hence that also is ruled out. Now there is a faint possibility that there could have been a transient ischemic attack in the brain, which led to the light headedness. It is just a lack of blood supply to the brain for some time. Hence if it is possible for you, a CT SCAN of the brain can be taken and a more conclusive test will be MRI.
Next you also complained of a feeling of fainting. That can be associated with the light headedness. Before you took off for the drive, did you have adequate food? Because it is possible that at that point due to fatigue or low blood sugar, you could have manifested all these symptoms. By the time you got the tests done, the sugar value could have auto-corrected. Hence i am asking you this question? Did you have any meal before you started the drive?
The consistent left side aching involving your shoulder and chest area with the tightness may be indicative of muscular spasms. Also since you consistently work out and do cardio, it is possible that the muscles are fatigued and you may want to rest for a few days. You are already in a very good shape and a few days of rest may be beneficial. I will still advise you Tab. Myospas twice daily after food for 5 days, and see if this consistent tightness and spasms are resolving.
The pins and needles mostly indicate a B12 deficiency. It will get better once you take the multivitamin consistently, but more importantly follow a healthy diet.
Can you give me more details about your smoking history? How many cigarettes did you smoke earlier on a daily basis? If you have consistently smoked for more than 10 years, it is better to get a X-RAY of the lungs just to check any restrictive lung condition, which develops due to smoking. That can also lead to some amount of chest tightness.
I will advise you at the end to get your BP monitored, around 3 values at different intervals are required to be able to come to a diagnosis. Mostly you can check your BP once on laying down, once on sudden dtanding from sitting position and once on sitting and send the values. It is also advisable that you get a CT/MRI of the brain done, just to rule out a possibility of TIA at that point. Because once this is ruled out, all the serious issues will be ruled out and all your causes can be attributed to muscle fatigue and a possible hypotension.
Will be eagerly awaiting your reply,
Feel free to discuss further,
