Brief Answer: Need more details... Detailed Answer: Hi, I see your questions has not been attended for quite some time which is a rare occurrence on this forum; perhaps its due to the complexity of your symptoms. To summarize, you report that you have neurological symptoms - sensory impairment with mild weakness on the right side - going on for 3 years. Do you mean you have intermittent spells or have you had the complaints going on persistently for years? I would also like to know your age and gender and if you have any other risk factors associated - diabetes, high blood pressure, heart illness, high cholesterol, thyroid abnormalities or vitamin deficiency. I am sure your doctor would have checked those. I would also like to know why are you on lyrica? Is it for the pain? If so, how much and how often are you taking it? I am sure this once side facial swelling is not due to lyrica / paracetamol. Neither does it have any connections to your past neurological complaints. If you can describe this bump further - exact size and shape of the bump, whether or not the margins clear and defined, do you have pain / redness / itching associated, and any other details - it can help me relate conditions better. Off course, a picture can be helpful. You might upload a good quality picture of the face and a close up of the bump. Awaiting your response... Regards
