50 year old male, prescribed Singulair 8 months ago to assist with allergy problems while taken allergy shot treatments. About 2 weeks ago started experiencing numbness/tingling in right foot, then both feet, the spreading up the body to above the waist. The best way to describe the sensation is a combination of the feeling you get when you hit your funny bone and the sensation when you sit or lay in a position that puts one of your limbs to sleep. Had all the blood work tests done at Dr. office to verify no other issues, all blood work is normal, Dr. suggested could be a neuorlogy problem and more tests will be necessary. Receive routine Chiropractic treatments and had him check everything, including new x-rays, nothing there. Read the side effects again for Singulair and realized that this numbness/tingling is just one of the symptoms I have had since starting this drug. The others being unusual weakness, tiredness, which I thought was just part of getting older and severe sinus inflammation, which I had thought was just related to my allergies. Have contacted my allergy doctor that put me on this and he said to stop taking Singulair to see if my side effects go away, since I am near the end of the time that he expected me to take them for anyway. I will repost after a few weeks or as soon as the side effects go away.
