Levulan Can The Use Of Aminolevulinic Acid HCL For The Use Of Keratosis On Your Scalp Cause Blood Clots?

Can the use of aminolevulinic acid HCL for the use of keratosis on your scalp cause blood clots? - levulan

I had a procedure called Levulan Kerastick from my dermatologist for the removal of keratosis on my scalp. The ointment is aminolevulinic acid HCl. 2 days later I had a small stroke. All doctors, including cardiologists and my dermatologist said that this procedure is not the result of the Levulan Kerastick aminolevulinic acid HCl. He said it was a coincidence that this has happened. I still have some doubts, and I wonder if anyone has had problems with this procedure. Thank you.
