S brown mostly black stool an adverse effct of 48hrs after endoscopy & flexsigmoidoscopy? Or side effect of med metronidazole and dexilant (dexlansoprazole)? Shd I wry

Yes, time to worry: Dark-colored stools may result from iron supplements, foods you eat (like a lot of spinach), substances (like peptobismol), but most significantly suggests bleeding. When blood is denatured by acid in your stomach, as from ulcers, stools will turn tarry ("melena"). Blood may also be ingested from nose bleeds, bleeding gums... Persistent melena, particularly after a GI procedure, needs evaluation. ...Read more

A drug reaction: If you have chronic recurrent hives (also called chronic urticaria), that is one entity, which often has no obvious cause and can be very difficult to treat (allergist, dermatologist or immunologist area). But if you get hives after taking a non-steroidal antiinflammatory drug, then you are allergic to nsaids-stop taking them; you may get a severe, life-threatening reaction one time. ...Read more

After surgery im taking antibiotic and pain releiver, 3 days after I feel like needle poking my heart and back portion. Is it pleurisy or drug reaction?

After surgery im taking antibiotic and pain releiver, 3 days after I feel like needle poking my heart and back portion. Is it pleurisy or drug reaction?

Post-op problems: Surgery may cause new problems to arise-- and one of them is the formation of blood clots. When these blood clots break loose and travel in the body, they often get trapped in the lungs-- which act like giant filters. This is called a pulmonary embolus or P.E. If it hurts to breathe in, or if you find you don't have much breath this could be part of the problem. You probably should get it checked ...Read more

Can Sympathetic Nerve Block procedure help/cure tachycardia/angina/vascular issues as well as pain that I've had after traumatic drug reaction?

Most of no use.: Synthetic nerve block had been successful, but I doubt that it will help in any of your conditions. I am not quite sure about if it will help in vascular issues as you have not specified about what veins and what kind of vascular problem, I also cannot answer about your traumatic drug reaction as you did not indicate what type of drug was involved and what kind of reaction. ...Read more

Medication for cystic acne & saeborrheic dermatitis causing severe migraines. Using isotretinoin, minocycline as HCl BP & desloratadine. Drug reaction?

Medication for cystic acne & saeborrheic dermatitis causing severe migraines. Using isotretinoin, minocycline as HCl BP & desloratadine. Drug reaction?

Stop meds, check eye: If you are having headaches, I would stop the Minocycline and isotretinoin. When given together there is an increased risk of a rare side effect, pseudotumor cerebri. I would have my eyes checked and if no evidence of pseudotumor, restart either the Minocin (minocycline) or isotretinoin, but not both. Migraines can also worsen with Isotretinoin and not affect the eyes, but it definitely needs to be ruled out. ...Read more
