hi, im 21 years old and have been experiencing great pressure behind my eyes, forehesd, temples, and nose for over a month now. My GP said its sinusitis but ive had antibiotics, anti inflammatories, nasal spray, anti histamines and decongestant tabs and nothing seems to b working. its stoppin me from doing things as it gets really bad some days. I also started having panic attacks, i think thats what they are, i get short of breath, go dizzy, pins n needles, clammy, shaking and a feeling of being choked! Please help!!
