I dont think because i dont really know. But even if i knew, i cant prescribe drugs to you
What i think is that you should have a little talk with the surgeon who operated on you asap on this matter. Most doctors prescribe drugs just to be on the safe side. You dont need a clot or something. But your doctors is the one to decide.
I am on Plavix for 3 months and aspirin and daflon for six.
Personally, i d take whatever is happening to you as a sign that the treatment really changed something that had to be changed, you know what i mean? I really dont think that it ll be like that for ever. Try to rest and give it some time. Things are now different inside your brain.
Hope it ll help your MS to subside.
Many of us have experienced weird stuff post op, believe me. Stay calm and let us know when this resolves. Because it most probably will.
WHATEVER YOU DO, KEEP YOUR DOCTOR INFORMED AT ALL TIMES.
