about 4 months ago I came across a small lump under my right nipple, I went to the doctors and was told they would give me a scan to rule out anything bad but later on rang me and said they don't think I need a scan, I was worried and got a second opinion at another doctors. she felt around my chest and armpits and said it seems like I have gynecomastia most likely from my weight gain. I said I also have experienced shortness of breath at night sometimes and gave me a inhaler as astma runs in my family. I again just thought I need to get this thing diagnosed with tests so I rang them up and requested tests and they gave me an appointment at the breast clinic this Wednesday. I'm happy I'm finally going to get it diagnosed but I'm really nervous about it turning out bad, today iv had a tight chest and last few days my chests bone has been tender to touch. I don't know if it's genuine or just me being worried and making symptoms appear. this lump has taken over my life for 4 months even when being told its nothing concerning I have been feeling my body up and down everyday and always think I feel something and tend to have an ache or pain in my chest or back which worries me. I'm definitely a hypochondriac but I just really scared something seriously wrong and all this waiting and going to different doctors has made it worse instead of being dealt with ASAP
